JRM 9 is a 30 card set which includes four different cards of Sadaharu Oh. Two notches were cut into the edge of each card by the manufacturer so children could shoot these cards with rubber bands! This could cause even more damage than flipping.
In this image, Sadaharu Oh, with arms folded, seems to be oblivious to the delivery about to be uncorked by Hawks pitcher Takenori Emoto. Since the Giants are members of the Central League and the Hawks play in the Pacific League, one might assume that this image is from the 1975 All Star Series.
This is a very high grade card from a scarce set by 1970s standards. Blank backed.
Size: 2 5/8" in diameter
Condition: Nm/Mt or better
