Earlier this year, I came across a couple auctions for loose packs from the 1970s. They're baseball cards, though they aren't Calbee.
For those of you with Engel's guide, this is JY 1a. At first I thought it was JY 3, but a quick look at the Lions logo shows that it's 1a. JY 1a card packs have Taiheiyo Lions logos, while on the JY 3 packs, the logo is Crown Lighter Lions. Additionally, there are the 11 copyright lines on the box, where the JY 3 box has 12 team copyrights.
There are 10 packs in my box. I don't know what to do with them right now. I don't have a type card for my collection yet. And the approximately 33% chance of pulling the best card in the set is pretty enticing. But I could probably find a type card if I looked in the right places. What do you think?
