Actually it wasn't Spiderman that was seen but rather the Spiderman symbol. It has been reported as showing up on buildings in cities such as Rome, Paris, Madrid, Rio, London, Berlin, Los Angeles, Tokyo, New York, London, Moscow, Seoul and Sydney. Big hype for the upcoming movie release this summer. It's kind of a let down for all of us that have read The Amazing Spider-Man #121.

You would think the one place  you wouldn't want to rob would be a comic book store full of superheros. A man dressed as Spiderman at a comic shop nailed a theif trying to steal a hardcore XMen book.

"Michael Baulderstone, 45, was dressed as Spider-Man as part of a fancy dress open day at comic Centre in Adelaide, Australia, confronted the man when he claims he spotted him taking the £100 book."
