My friend James Gurney is the creator of Dinotopia, and he is a sketching fanatic. When I had lunch with him at Bob's Big Boy in Burbank a couple of years ago, he and his wife (also an artist) stayed at the restaurant after the meal to sketch street scenes. He just posted this excellent short video with a sketch he made of some men at the Santa Monica pier.
In 1981 I drew a portrait of two guys on the Santa Monica pier, then asked them to describe themselves into a tape recorder. For the first time, their faces and voices are brought together in a talking portrait.
