Earlier this week, AICN took a snapshot at the Licensing International Expo in Las Vegas of what looked like an official teaser poster for Spider-Man 4. No one was impressed with it--looking like a rehash of older posters with no actual new image of spidey and just a big number "4" in the center.
Now SuperheroHype has found out that neither Sony/Columbia nor Marvel had anything to do with it, so it is NOT an official movie poster.
Stay tuned for the real deal closer to the May 6, 2011 release date.
