uhm, no. you have to prove that to me. all i have is your say so. that's not very much.
however, if it's a direct lift, then it's still a nifty design, however poorly exectued with that type in the white space. remember it was a little cartoon image in a comic book (assuming it's a lift) and not a poster/advertisement. different function and thinking involved here.
but even with that said, if it is a direct lift, it's probably just lazy and more than a little stupid. he should have just drawn his own version and nobody would ever have known to cry bullshit. you don't have to be a rocket scientist to draw an image like that.
one thing i want to point out on this poster is the way it assumed the actual edge of the paper is the edge of the visual and conceptual frame. many poster artists feel the need to put their image or design inside some sort of frame (sometimes and actual drawing of a picture frame, no less), when the edge of the paper acts as a visual frame already. sometimes, it starts to look redundant and even claustrophobic (like the edges are moving in on the viewer.) now, those tensions created by too much framing can be useful if it's part of the intent of the mood of the piece, but ususally it's unintentional and sorta ruins what is trying to be achieved.
so, think about how well this design actually uses the piece of paper itself as an essential element of the overall design.
it would almost ruin it to mount it in a real frame and hang it on the wall.
wow! i've never seen one of these in anything but b&w. they were little xerox things drawn by a guy named kevin clark. he lived in seattle in the early 80's for a few years and then moved south (l.a., i think). lost track of him. somebody told me he became big in the skate community back then. i always loved his stuff. if anybody knows what happened to him, i'd love to hear about it.
all that said, i think this is a pretty cool, very effective little piece. my only crit would be that i think the type stuck in the upper right white space should have been tucked below and the space left open. when people lay things out, they tend to want to "fill holes" (usually with type) in the design. it's a natural tendency. but sometimes, the empty space in the layout may be the most important thing in the tension created by the design.
