Well, I saw this card listed on a small auction listed as "EUNO FRANK". Clearly whoever did the listing isn't a baseball fan and couldn't read the signature. In any event, I did't recognise the card but a bit of searching showed that it's a 1967 Dexter Press card.

I've got to say that I really love these cards, they just look great. I think I'm going to start building this set. How did I not know about these before?
Anyone else collect Dexter Press cards? Let's see 'em.
