Not sure exactly what you're meaning... Have the artists do their rendition of 'hamsters' for example and end up with a bunch of hamster sketches from various artists?? lol.
I am working on having specific artists complete a favorite comic cover of mine. The first will be here later this week. I want to eventually get Hall, Tan, Laurange, and a couple more. Kind of like what you're thinking, just a different style/medium on each.
2012 2013 2014 2015 2016 be the year Panini finds Marvin Harrison & Marcus Allen to sign their NFL's Greatest Signatures cards?
