Have You Seen This Dodger Tray Before?

From time to time I'll get an email from a collector wondering about an item they have that they know nothing about. A couple of weeks ago was one of those times, and I have to admit that I'm stumped.

What we have here is purported to be a Dodger lunch tray given out during an Opening Day Lunch event at the Coliseum in the late 50's. It was called an Opening Day Picnic. Fans could have lunch on the large outfield grass (I'm assuming beyond the right field fence) catered by the team. The emailer said the original owner was served steak and salad set atop the above lunch tray with some notable Dodgers drawn on it.

If you happen to now anything about this event please let me know. I'd love to know more.

On the tray are face shots of Johnny Podres, Don Drysdale, Maury Wills, John Roseboro, Duke Snider, Wally Moon, Sandy Koufax, and two players on the bottom right who I can't exactly place. Maybe Charlie Neal and ?
