flickr is big on encouraging people to leave comments on each other's photos. This is generally much appreciated, but there are a number of "standard comments" that turn up frequently that are a bit daft.
Anyway, a while back, Stuart went into Kelvingrove Art Galleries and applied various such comments on peel-off sticky labels to the walls next to a selection of artworks. He then photographed them and removed them (though it would no doubt have been funnier - if more enraging to the museum staff - if he'd left them).
But now the flickr group "flickr in the real world - instant fave!" have muscled in on the idea and produced wee cards along these very lines!
Stuart should clearly sue...
