Landlady Lyn Anderson discovered the 7ft artwork hanging from the chimney stack of the Britannia Inn, in Tewkesbury, Gloucestershire, on Friday.

The picture quickly drew the attention of passers-by and motorists, and fearing it could cause an accident, Mrs Anderson called the fire brigade.

The poster was removed and police say they want to speak to the culprit.

"It was a hand-drawn picture of a man standing full frontal," explained Mrs Anderson. "But he had something covering his bits, thankfully.

"I phoned the police because I was worried it might fall down and the officer couldn't stop laughing. The fire brigade came to remove it and they were all in stitches as well.

"A bit of a crowd had gathered. The locals loved it - it wasn't really offensive - and they couldn't stop laughing."

A Gloucestershire Police spokeswoman said the incident was not being investigated as a crime but that officers were keen to catch up with whoever was responsible to warn them about the safety implications of the stunt.
