Here's the completed poster. Tom, you are correct. There have to at least be two designs. I have a couple cards that are missing from this one I have pictured altogether.
Looks like it's a 6x7 so 42 cards total. I suppose this gives me an excuse to work on a 19th century project which I don't think has ever happened before for me.

Thanks for the insight everyone!
