Where's Frank?

Frank is a new film released on 9 May, co-written by Jon Ronson and starring Irish charmer Michael Fassbender.

Last night I noticed a Frank Sidebottom head stuck on a shop window. I thought it was a random sticker but on closer inspection realised it was a plastic type material that stuck to glass. 

How cool! Then everywhere I looked there were more....

...and more!
