one of my favourite things to do whenever i visit an art museum of some kind is to browse the gift shop and see what cool posters they have for sale. there are almost always really different and well designed graphic treasures to find, as well as the classic art exhibition posters (think , etc) that can really have an impact on your home decor without spending too much cash. i found the on Etsy and they have some really unique posters in their shop, many i have never seen before. besides the requisite that are always so cool, they have a lot of and a cool section of that have this sixties (of the Beatles fame) feel to them. i but their is worth a browse.
