Harry Potter Poster Signed by Illustrator Deathly Hallows Approx 22 x 28 inches
Here is the story about the poster
My girls were HUGE Harry Potter Fans and so we made it a point to go to the Barnes and Noble Book Debut Party July 21, 2007.  My Oldest dressed as Moaning Myrtle with a toilet seat around her head and WON the costume party!  This was the prize.
I can't read the  illustrators signature, but it did come from Barnes and Noble and I believe they gave these away at all the Stores for their costume party that night. I believe they were different posters with different illustrators at each store or something like that.?
It has never been displayed or out of the cardboard tubing for more than a few minutes since 2007
Any Questions, please ask.  I'll do my best
