OK, I entered a Valentine ATC swap.
You may be asking yourself "what is an ATC?" well, I'm still asking myself that so dont feel bad.
Apparently it stands for Artist Trading Card
Here are the 3 rules of ATC's. Copied & Pasted!
1) ATC's are always the same size 2.5"x3.5" (or 64 x 89 millimeters)
2) ATC's are *ALWAYS* traded and *NEVER* sold.
3) ATC’s are always signed and dated by the creator on the back of the ATC.
There are no other rules...and I mean NONE. Make ATC's out of anything, about anything, with anything and for anything. Use whatever you have … and just play!
