Polaroid eyewear print ads from Brazil

Picture 1-49
As far as I can suss out by Googling, these print ads for Polaroid sunglasses were developed for Brazilian readers. Either Dan Clowes did the illustrations or someone was aping his style. (If the scans were big enough, I'd be able to tell for sure.) Link | (Many more Dan Clowes posts on Boing Boing here)

Update:

Jenny Ryan let me know that Fantagraphics has more information about this. It's not Clowes, but it sure looks like him. Nick Parish says the illustrator is Felix Reiners. Why didn't they just hire Clowes in the first place?
