I have been a big fan of traditional silhouettes since I was a kid, there is something obviously mysterious about them! Wikipedia says this, "A silhouette portrait can be painted or drawn. However, the traditional method of creating silhouette portraits is to cut them from lightweight black cardboard, and mount them on a pale (usually white) background. This was the work of specialist artists, often working out of booths at fairs or markets."
I think this calls for a new silhouette project this summer, stay tuned!
