BATMAN-HELLBOY sketchbook piece

I recently started a large 11x17 sketchbook featuring my two favortite characters of all time, Batman and Hellboy. I decided to shoot for the moon and run the idea by Mike Mignola himself. Much to my surprise and despite the fact that he does NOT do commission work (please dont use this as a catalist for inundating Mike with commission requests), Mike was kind and generous enough to grace me with this amazing gift . Needless to say, of all the art in my collection, this one holds and extra special place in my heart. Another cool factoid is that Mike said that this was his personal favorite thing hed drawn in ages. See the Adam Hughes BM/HB piece in this gallery for the other entry in the sketchbook. Looks like this book is off to a stellar beginning!
