The blue one seems pretty obvious. The world's fair was held on Treasure Island (in the S.F. Bay Area) in 1939. Not long after that it became a Naval base.
does anyone have this same worlds fair sticker? have seen a few different ones but none like the one I have. could this be the only one left!!! I smell collector item!
