I bought this sketch on eBay from Spiderweb Art Gallery. Their eBay seller I.D. is spiderwebart. They are the Offical website for the Hildebrandts'. This was a preliminary sketch used for a Rogue trading card for the 1994 Marvel Masterpieces card series. Please go to the link on the previous page to see the card from the 1994 Marvel Masterpieces card set, that this sketch helped produce.
