Way back in the year 2006, I drew some Law & Order: SVU Valentines. They were the first thing I did that went immediately super-viral; I got nice emails from a bunch of cast members and behind-the-scenes people, and one year Hargitay and Meloni even bought a whole bunch to give out as crew gifts.* So for sentimental reasons, I always try to keep some sets in stock. Cards measure 2" x 3.5" and each set includes the eight designs shown plus little envelopes.
*Despite that rad story, these are NOT an officially licensed product, which I feel like I should mention so that no one confuses them for one.
