L to R: Irving Brown, Clarence Craig, Louis Cohn, Joseph Bernstein, w Les Cohn, Clarence Craig's son, and Harvey Jacobson at Wynn Oil Trade Show. See notes.

"It was taken at an Auto Show, probably at Municipal Auditorium in downtown Kansas City, MO. The other men were sales people who sold for Zayda. The company was Sunflower Distributing Company and they were demonstrating the benefits of Wynn friction proofing using "friction machines." A roving photographer was taking pictures of all the booths and exhibits and sold the pictures."
