Educate me on the famous Cinci Card.
I have read all I can find online about it and know Leon has one of the cards.
Was it offered only to customers of the store which produced it? How many theoretically survive? Is it far more rare than the Plank or Wagner T206 cards? I have seen images of it in Red ink and Black ink which is the most "common"? Also what were the sizes of these cards.
Very interested in it's history and I made my own personal reprint (clearly marked and for my personal use) of it from an image I found online. I would just like to know more about the card's production and history.
