I recently did a few sketch cards for the very limited "master set" series for 5finity's P'ups (pinups and puppies) card set.
Here are my cards, and you'll notice, all of them are chihuahua puppies, since we have a chihuahua, and artists had to work from a list of breeds on the regular cards (only being allowed to draw one of each breed)...
I also have one additional card available for sale for $75.
Email me if you're interested - email@example.com
(Or it's on eBay HERE)
