This piece was not originally started as part of my ongoing series of biologists and naturalists. It's a commission for Toni, the woman who had my Darwin illustration tattooed on her leg. Wallace is going to be a companion piece for the other leg.
A framed print of this piece will be included with my series on display at Irvine Nature Center (www.explorenature.org) in Owings Mills, MD from May 18-July 30, 2011.
The opening for the three artist show, entitled "Delicate Visions: Rebecca Clark, Joanna Barnum and Elaine Brandes," will take place on Friday, June 3, 5-7pm.
