I love all of the old vintage science charts with their saturated colors and intricate examinations of plants and animals. Chronicle books recently put out a wonderful book full of old charts that are really so beautiful. There are many replicas available these days in design shops--but if you look hard, maybe at a more out of the way flea market, you may find some original ones.
I am particularly fond of the muted black and bottle green charts where the subjects really pop.
I am on a scientific chart rant with the plates right now--having fun applying the color and the sensibility of these wonderful vintage props...
I'll be doing lots more of these-on plates, platters and bowls.
