I recently did this to my kitchen counters....
I collected ad's from the 50's, 60's and 70's.. some are real and others are retro art. It was lots of fun finding pictures and some crack me up (Santa smoking) . I covered the entire kitchen counter (it wraps around the room) with the exception of the sink. It took days to seal and the smell was awful but everyone that sees it loves it.... such a fun way to spice up an old countertop.
and this is a mural a friend painted in the "dog room"
the image originally was on the Beatles Apple Boutique building in London.
