These delightful pop-graphics -- if I may so dub them -- were scanned by me from New York freelance illustrator Yuko Shimizu's first monograph, published by Gestalten in Berlin in 2011 [Amazon].
Yuko was kind enough to pass on a copy of this (very) handsome book recently. It features a comprehensive overview of her comicesque and culture-melding graphics (she's originally from Japan), produced over the last decade or so. It is a beautiful product and highly recommended.
Previously: Yuko's Progression from two years ago shows the evolution from sketch to final illustration in Yuko's work. There's also links to interviews and the like.
