They put the mural there in 1997 as a temporary thing to hide the derelict building until it was knocked down... now it looks as though they like the mural, and have kept the building, lol. I've always liked Swanage, I spent many happy hours there as a child - it's a town with a great sense of humour and has several murals by the same artists.
