That was a Street Rodder Magazine project car, back around 1974-75... I grabbed that shot, in the rain, at the 1975 NSRA, in Memphis, using the little Kodak 110 instamatic camera that I had received, earlier that summer, pas an 8th grade graduation gift from my grandparents.
Before that I was using an ancient Kodak Brownie, that I bought for 50 cents at a yard sale..... I have been playing around with car show photography for a long time.
