In our 37 years of buying, selling and auctioning Japanese sports memorabilia, this is the first time we have ever encountered this calendar. Sadaharu Oh and Shigeo Nagashima headshots appear near the top, with their names printed in Japanese text. At the very top is a wheel which can be used to realign the days of the week with the calendar below. The back contains blue tint in-action images of Oh and Nagashima. There is no information on the product which indicates the manufacturer.
Size: 3 1/8" square
Condition: Vg. Some foxing on the reverse side.
