Carvings riddle stumps villagers
Puzzled residents across Yorkshire are turning detective after mysterious stone heads were left outside their properties in the dead of night.
The sculptures feature the same carved symbol and come with a riddle attached.
Despite CCTV film showing a man leaving three heads outside a post office, their origin remains unknown.

Reminds me that artist guy who makes big sculptures resembling a Lego man and then turfs them into the sea so they wash up somewhere... Bask in press.

Next year for BTOTB a guerilla campaign to install art in peoples gardens? But keep it stumm?
