In Fall, I got hired to illustrate not only the signage for the latest special exhibit at the Conservatroy of Flowers, called, The Art of Aquascaping, but also to illustrate a collectible art poster and other merchandise to be sold in the Conservatory gift shop while the exhibit is showing (Dec 14 - April 15).
This poster was a beastly drawing! 4' long, 18" high. The prints are coming in any day. You can see a higher res one under "wildlife illustration" under the scientific Illustration gallery linked from the top of the page.
The Conservatory gift shop also has mugs, glasses, and shirts, all drawn by yours truly!
