At this point, anywhere. Once you get to a point that things are being referenced that you haven’t read, then you go back and find the referenced issue.

You also might want to specifically search for a series that had a limited arc so there’s a finite amount of issues to read through.

And if you don’t care about “cannon”, I remember loving the “What If?” and “What The–!?” series. Very much has the vibes of kids talking about “What if the Wolverine was also The Hulk” …

So the important thing to keep in mind is that there are different “corners” of the Marvel universe and while they can and do intersect and collide, you can happily sit in one corner, completely unaware of the others.

Edit My wife also suggests Marvel Unlimited so you can dip your toes in, experiment, and find what you like. I, for example, never cared for Doctor Strange, but got sucked in by The Death of Doctor Strange, Strange, and Strange Academy.

The big ones:

X-Men: Recently rebooted with new number ones across the board, really my introduction to Marvel. Mutants trying to live in a world that hates them.

Current books: Cable: Love and Chrome, Deadpool/Wolverine, Giant Size X-Men, Wolverine, Magik, Rogue: The Savage Land, Laura Kinney: Wolverine, Psylocke, Storm, X-Men, Uncanny X-Men, Wolverine and Kitty Pryde, Exceptional X-Men, Weapon X-Men, Phoenix, X-Factor (ending), Nyx (Ending), X-Force (ending), Juggernaut, Kid Juggernaut.

Spider-Man: Marvel’s most recognizable character. Generally street level super-heroics. If it’s something that’s going to break the planet, that’s outside Pete’s scope.

Current books: Eddie Brock: Carnage, Spider-Boy, Venom: Original Sin, Spider-Man and Wolverine, Amazing Spider-Man, Miles Morales: Spider-Man, Spider-Verse vs. Venomverse, Spectacular Spider-Men, All New Venom.

Avengers: Easily recognizable by people introduced to Marvel by the movies.

Current books: Avengers, Hulk and Doctor Strange, Incredible Hulk, Iron Man, Vision & Scarlet Witch, Immortal Thor, Amadeus Cho, Sam Wilson: Captain America, West Coast Avengers.

THE BIG CROSSOVER: A few times a year, Marvel throws a monkey wrench into the works by having a giant crossover event that messes with the continuity of all the books. It’s annoying, but limited in duration… well… until the next BIG CROSSOVER.

Current books: Doom’s Division, Doom Academy, Fantastic Four, Superior Avengers, Thunderbolts: Doomstrike, Doctor Strange of Asgard, One World Under Doom, Red Hulk.

Alternate Universes: Technically Marvel characters, but outside the plotlines of the normal Marvel Universe. Generally self contained.

Current books: Ultimate (Fill in the Blank, X-Men, Spider-Man, Black Panther, Ultimates), Daredevil: Cold Day in Hell (really good!), Predator vs. Spider-Man, Gwenpool, Hellverine, Deadpool, Deadpool Kills the Marvel Universe One Last Time, It’s Jeff the Land Shark, Spider-Gwen: Ghost Spider, Godzilla vs. Spider-Man, Hellhunters (good book!), TVA (REALLY good!), What If?

OTHER: Not neatly fitting into the above categories.

Current books: Fantastic Four, Punisher, New Champions, Moon Knight: Fist of Khonshu, Infinity Watch, Daredevil.

What kinds of stories are you interested in? Do you want a teen hero or an adult? Are you interested in the main character being female? Do you want it to be serious or funny? Do you want stories where the world is threatened, or just stories involving a neighbourhood?

Of the 6 in the image you shared, I think I’ve read them all, but I honestly don’t remember the Hawkeye ones very well. Hawkeye had some great storylines, but I just don’t remember those ones by the covers.

Civil War had its own movie adaptation, but the comic version is much better. It involves heroes fighting heroes. It involves heroes choosing sides for what’s most important, is it individual liberty or is it collective safety? It was a huge event that had tie ins in dozens of different comic books. It’s a very big event, I would guess that a full book will still miss out on a lot of peripheral stories in say the Spider Man comic books. It’s great, but I’m not sure it’s a good place to start.

House of M was an amazing story. If you watched the WandaVision TV series, it’s similar in that you don’t know what has happened to reality. This is also a huge event that crosses over all kinds of other storylines. But, this one might be something you appreciate more if you’ve been reading Marvel Comics for decades. It upends the entire world, and so you need to know a bit about the world before you appreciate everything that happens.

Ms Marvel is on the complete opposite end of the scale. Instead of world-changing events, it’s a teenage girl with superpowers just trying to figure things out with her friends. Instead of being epic, it’s just really charming.

Old Man Logan is also another one that’s probably mostly going to appeal to people who have been reading Wolverine for a long time. It’s a great story, but you appreciate it a lot more if you’ve been reading Woverine comics for a long time and know what makes him tick.

What I think makes sense it to start small. Don’t dive right in with the full Civil War or House of M series. Start with just one hero or one team, and start with the stuff that’s currently being published. You can always go back and read the big events later. But, it’s less overwhelming just to pick up where things are now and find out what kind of stuff you want to read more about.

I think Free Comic Book Day just ended, so you might not be able to get them free anymore. But, often the Free Comic Book Day releases are a good place to start. They know that people will be jumping in for the first time, so they make them accessible. The other good way to go is to get a recent #1. Apparently a new Amazing Spider Man run just started, so you can start with issue 1 and go from there. Laura Kinney: Wolverine is at #5, so you wouldn’t have to go back too far to get the start of that one.

tl;dr: Start small, start with something modern/recent. Figure out if there’s a hero or a team (or a writer or an artist) you like, and use that to explore more. If you like what you’re reading, you’ll figure out what to read next. If you don’t like it, move on to something else.

Check out the old AvP comics

Out of what’s in the screen shot, I’d order them right to left, bottom to top, with the Hawkeye on the top row being the exception.

The Hawkeye and old man Logan stuff is superb, and relatively self contained.

Ms Marvel is great, but it’s less of a jumping in place to marvel. Damn good title, just might want to start with stuff that’s less likely to bounce around as much.

The other ones are solid reads, but they might not make much sense until you get a bit deeper into the marvel comic universe
