This one-of-a-kind sketch cover to Hulk (2008) #1 was completed for the Hulk 100 Cover Project by former Hulk artist John Romita Jr. and colored by artist/colorist Aaron Sowd.
This is one of two different covers completed by the duo.
In a blog posted by Sowd, he mentions that this cover brought over $1000 in the Hulk 100 Project Auction.
After the images were completed, Sowd was asked to color and embellish the images.
