Joe, I do have a pic but I'm having trouble trying to post it. Anyway- on the night of May 27, Len Zito debuted the car and only made 2 laps in the heat &consi. There is a photo of him in the program and it looks just like the guy in your photo-
As a side bit of trivia, Whip Mulligan drove the Marinelli M-1 to 6th in the feature that night. I would say that race was his last time in a car as far as I know.
