Thinking it was just a nice reproduction, he bought it and took it home, where he discovered a faint signature by the Spanish artist.
"I started shaking a little bit," Mr Bodish told the newspaper.
"I realised it wasn’t going to make me rich, but still, how often do you find a Picasso?"
In addition to the signature the poster was numbered 6/100 and had "original print, signed proof" written on it in French.
Experts have estimated the poster could be worth up to $11,500.

Recently my mum received an email from a chef in Melbourne asking if this painting was one of hers. Painted in 1969, this Kangaroo Point landscape was purchased from a Chapel St opshop. It seems she is in good company.
