I finally decided to bite the bullet and buy a card that's been on eBay for quite some time. It fulfills a longstanding need on my Archer Sketch Card Artist List and at this point I really can't pass up anything that knocks off another name from that project. It isn't my favorite sketch so I was holding out hope another would pop, but it has not and I had some unexpected funds to play with.
Greg Kirkpatrick leaves me just four short of completing this decade-long quest of one sketch card from each artist to contribute to Cryptozoic's lone Archer trading card set.
