Saw these at a local store, I believe by a local artist. Kinda cool. They had others, as you can see on the fringe of my photos (such as GI Joe, Thundercats, etc.). This next one was my favorite, since the source material lends itself so much to this style. EDIT: Found the guy's blog. Lot's of good stuff. You've probably seen some of his work around. http://montygog.blogspot.com/
Dave Perillo is from the Philly area I believe. I've done a few local art shows with him. Always does great stuff.
I have seen some of Dave's work before, and though it is a style many people are using these days, I still like them, and the subject matter is of course awesome. I really dig the karaoke one, totally love the vintage happy, stylised version of every one of those characters.
I have a t-shirt with the karaoke print on it. I love it. Hadn't seen other stuff from him, I'm liking it.
