Well, I didn't actually attend Motor City Con, but thankfully a friend of mine did. I'm a huge Paul Pelletier fan and, unfortunately being a western Canadian, I have never had the chance to see him at a show. Ever since his rep at mightynib.com retired, its been hard to find out just what stuff he might still have and what all has been sold. I asked my friend to check out the pages he brought and look for any featuring Valkyrie, Gamora, Medusa, or Squirrel Girl. He found a couple of pages for me. A nice little page from Fear Itself: The Fearless with Valkyrie, and a sweet page from the Secret Invasion: War of Kings One-Shot featuring Ronan, Medusa, Black Bolt, and Crystal. Always ecstatic to add any Pelletier pages from GotG or War of Kings to my collection.

From others' posts, it looks like Motor City Con is a pretty good con. Might have to actually attend myself one day!
