Flat Plastic Bat with Facsimile Signatures
 

Hi-

I purchased this item in May at the Brimfield MA antique show. It is a flat plastic bat and it says "When bird is caught ball is hit". It has facsimile signatures of Doby, Berra, Snider and more. I assume it is from a game but does anyone know what game it is from? Any idea what year it was made? Any other information about it would be greatly appreciated.

Thanks in advance,
Alan
