I don't really collect a lot of comics memorabilia--I don't really have any statues or many posters or anything. But I do have a few things I like.
This Beta Ray Bill poster, an original teaser poster for Walt Simonson's run on Thor, is pretty damn sweet--great drawing, with classic Simonson energy flares. I love the graphics treatment as well, with the left/right split of the background space which helps focus on the silhouette, plus especially the targeted use of red. It's printed on fairly nice matte paper as well. Picked it up at a garage sale run by a guy who used to own a comics shop!
I've always enjoyed watches with a fun/cool image. My last watch was a Neitzsche watch, and when that broke, I got this, which I think is great. It's not rare or anything, you can get it on Amazon, I just like the idea that out of the ten or so watches that Marvel makes, one of them is J. Jonah Jameson! Fun idea. As a friend of mine said, it would be great if it had an alarm that said "PAAARRRRRKERRRR!!!!" I know watches are becoming an accessory of yesteryear, but I still like the way they can still make a small statement about your style or interests.
And last (and probably least) is this Scourge button. I got this at a comic con years and years ago. It's just a sweet panel and reminds me of when I first started getting into comics. I was always a fan of Scourge.
I guess I have a few more things, but those are the ones that I like the most.
