nope, but wish I had one once. Instead, I left one of my cards on the monster with the DML web address. Never got contacted and don't believe the person is on the list. Never saw the monster again, either, even though it was parked in front of my building on base.
IIRC, I just printed it out on some of the 8 1/2 x 11 laser-perfed business card stock, although I recall I had to fiddle with the printing margins to get it to register the images a little better on the cards.
