Looking for something different to collect and use to decorate a wall in your house? There was an exhibition of part of the donated collection of 12,000 shopping bags used at department stores, political events and other shops or events where things needed to be carried. Some were autographed by the designers including Andy Warhol and Roy Lichtenstein. And there were bags from every Presidential campaign since 1948. The bags were made of paper, plastic, metal, glass, and maybe more.
