up for auction now is a bag of 1975 Calbee Pro Yakyu Snacks. These were the snacks that the early series of the Monster 1975-76-77 Calbee set were originally sold in.
The text on the back says:
- Calbee Snack Pro Baseball comes with new 1975 edition pro baseball cards
-If you get a Home Run card you can receive either an "Album" (for putting cards in) or a "Pro Baseball Book".
- The Pro Baseball Book contains an introduction to all the players on both Central and Pacific League teams in 1975, a game schedule, stories about major records and famous players, baseball history and its rules.
The seller helpfully reminds potential purchasers that these 45 year old snacks are not for eating, just for collecting.
