In no particular order (except shirts first)...

The P-47 Thunderbolt
This is currently for sale at Spreadshirt in its original colors and also on slate. At the moment it's the only one up there because the others were removed in anticipation of Shirt.woot's second Double-Take Derby. Turns out only one got accepted, but that's okay, I was honored to be chosen at all. ^_^;

Tiananmen Tank Man

Cheese Dreams
Chosen by Woot! for the Double-Take #2 Derby. Didn't do as well as in its first run.
Now also available on Spreadshirt.

Pinwheel
Posted to Spreadshirt, although the women's tees are a bit altered.

SunBite
Available in my Spreadshirt shop.

1984: Soyuz T-11 Launched

1984: UN Condemns Chemical Weapons
Few people liked this design, but I'm strangely drawn to it.

Dragon's Hoard
I have a dragon complex. Always have, always will. The cranberry American Apparel shirts are also beautiful, so I felt good making this design.

Crash
This was a shirt design but I don't think it makes a wearable shirt. I just like the wings.
All of those except Pinwheel and Tiananmen Tank Man were hand drawn, then scanned in and worked in Adobe.
