Yes, but is it art?

Here's one in the eye for Marcel Duchamp! I hasten to add that this photo was taken in foreign parts (Prague). We Brits are a bit stuffy about this sort of thing. But is it art? Is it American art? Didn't Roy Lichtenstein do something like this? Should it be on display in Tate Modern, so that all the pseuds can discuss its deeper meaning: Man's answer to the Guerrilla Girls, perhaps? Or should it be relegated to the little boys room at the Tate as a mere convenience. More importantly, can little boys actually reach it without jumping?
