The idea of a popup gallery isn't a new one – unless you're a graffiti artist. Banksy started the tradition of the Santa's Ghetto: Christmastime popup galleries that featured Banksy's work printed on canvas. The exhibits were held in venues like warehouses and pubs and were of very duration – three days or so. They started small – in neighborhoods in and around London and once even in Palestine – but within three years the shows were nearly selling out. During a 2003 exhibition, Banksy entered the north London warehouse housing a Santa's Ghetto, only to see police asking one of the exhibition's staff if Banksy was there. "'I'm sorry I can't help, I don't know who Banksy is,' the staff member lied. 'But just as I was saying this I saw Banksy stroll into the exhibition. He must have seen the police at that moment, because he moved along quite quickly as though he was looking at the paintings and then very calmly walked out again.'"
