Also sitting next to us was Jim Soldo and his style really amazed me. He would draw standing up with 2 different colored crayon type pencils looking down so basically upside down. The time it had to take to train yourself to do that is mind boggling I tell you. He was a lot of fun and gave my sister and I a drawing. She got a dog and I got the girl face (kinda reminds me of Pat Benetar). Go check out his web pages here (he was doing the ambidextrous drawing so check out that tab for sure)
