Fig. 25 Playing Cards is a detailed tribute to Erdnase and the infamous Expert at the Card Table book. Not only do the decks include illustrations from the book, each deck is uniquely wrapped to look like a mini replica Expert at the Card Table book. 

The cards themselves are elegant, having custom back designs with METALLIC inks.

Why are they called Fig. 25?

S.W. Erdnase stated that the most important "artifice" one could master with a deck of playing cards is the bottom deal. The M.D. Smith illustration for this invaluable lesson is fig. 25.
