Now this could be seen as taking the pee . . .

I am indebted both to the unknown graffiti artist and the photographer with the presence of mind to snap this one.

It's another little French connection, recalling dear old Marcel Duchamp's Fountain of 1917, in fact simply a porcelain urinal, signed and dated under a pseudonym.

He submitted it as a joke to a New York art show, whose organisers proclaimed that they would accept any exhibit. Actually they didn't display the piss de resistance, thus creating more of a story by bottling out.

The original Fountain was lost, probably thrown away (can't think why . . .) so eventually Duchamp authorised 11 official replicas, which you may see in the world's great art museums, and possibly various antique Gents' toilets.

An official Fountain was sold at Sotheby's in 1999 for $1.7 million. I expect you can get a new one at Bricodepot for about €20 . . .

In 2004, Duchamp's Fountain was voted the most influential artwork of the 20th century by 500 selected British art world professionals. You couldn't make it up. Must go and let some out.
