It's hard to pull off a truly surrealistic collage these days (mostly they just look weirdly piecemeal or lame!) but artist Sammy Slabbinck uses vintage magazines from the 1950s-1970s to create intriguing environments in his work. And I think they look amazing, don't you? I particularly love the boxing ring one (sort of reminds me of this!) because the disjunction is both seamless and singularly odd.
