MOO cards

here's a bit of the MOO cards that I've had printed up for me. The 6 in the center are some of the 50 free business cards that I got from them. They are sort of a cross promo because the fronts of the cards has MOO's information and a promo code to get 15% off of printing with them.
The mini cards around those are from the daily comic I used to do.
I added notes to with links to larger versions of everything!
