What Avenger's trade should I buy?

My 8 year old cousin wants an Avengers trade as a gift. I have no idea what trade I should get him. Any suggestions?

@sagejonathan: Do they like any heroes or villains in particular?

And as an 8 year old, are they mature enough to enjoy normal comic books, or is it all ages stuff you're looking for?

He said he likes all super heroes. I think a regular comic would be good but not too bloody is all.

@sagejonathan: If he likes Spider-Man, Wolverine, Hulk and Ms. Marvel, The Avengers And The Infinity Gauntlet is pretty good, and is all ages, so it's not too violent.

I'll have a look through my collection of normal comics and see what I can find though.
