Rare Sighting

I was doing some looking around on Yahoo! Japan Auctions the other day and I came across something I've never seen before - an empty bag for Calbee's Yakyu chips from 1973, the first year Calbee did baseball cards.

I swiped the images from the auction to share here.  As you can see, the bag's not in very good shape which isn't a surprise since it's almost 42 years old.
