I've already posted a couple of topics for my Harry Potter and Lord of the Rings cards, but I thought I would make a new topic for any and all cards I may do in the future so I won't have a topic for every single subject matter.
A sketch card is a small collector card size artwork that can be gotten from certain packs of trading cards like Lord Of The Rings Evolution produced by the Topps Company (the people who do sports cards) or by commissioning an artist to draw one of exactly what you want.
This is a commission work I did for a guy in England. He collects Darth Maul sketch cards. 2.5" x 3.5" watercolor, pen and a tad of white prismacolor pencil.
