Cans featuring 4 of the upcoming movie Avengers.
From l to r:
Black Widow (Diet Dr Pepper) - Part of the 2010 Iron Man 2 Dr Pepper collector can set
Captain America (7up) - Part of the 2011 Capt America 7up can set
Iron Man (Dr Pepper Cherry) - Part of the 2010 Iron Man 2 Dr Pepper collector can set
Thor (Dr Pepper) - Part of the 2011 Thor Dr Pepper can set
I'm only missing a Nick Fury can that came out with Dr Pepper Cherry. He was extremely hard to find.
Dr Pepper currently has a 2012 collector can promotion for The Avengers movie. It's a series of 8 cans featuring all of these characters.
