I think this is the best piece of street art I saw in 2010. It was in Melbourne, on Collins Street, right up the posh end. It caught my eye from a fair distance because It was placed on the edge of a building so most of it was flapping in the wind. Not only was the subject matter an age-old classic, the placement and the flapping pure genius, it was subtly Christmas themed. Was it a comment on Christmas itself?
