I did a lot of flower studies in the early 1990s and many of them appeared on this Blog years ago. I am especially fond of irises and it is iris blooming time in the northeast USA just now. When a group of friends asked me to do the T-shirt/program design for a convention featuring, uh, erotic science fiction, I designed this rather explicit iris for them. It was printed in white on a purple T-shirt and I still have mine and I still fit into it, too. I have designed dozens of T-shirts in my time, but not so many now since I am not doing the "fannish" thing so much.
Original drawing was ink on illustration board, 8" x 10", June 1991.
