Question for 1951 Topps game experts
 

I have been trying to learn more about the 1951 Topps Doubles Baseball Game, but I am having trouble finding information about the paper “game board” that was issued. I can’t even find a picture of what the game board looked like, are there any surviving examples of this? If so, are they rare? How do I find one online (even if just to see what it looked like)?

Also, where can I find the rules of how the game was played? Everything I have seen just talked about the cards themselves, how red backs are more common than blue backs and that there are two variations in the red backs set because they updated the team that those two players played for when they were traded mid-season. This is great information, but I am at a loss for trying to find more info on the game itself, where I might find a game board (or at least a picture of one that I could reproduce if they are super rare and beyond my budget)?
