I have a dual set of Congress playing cards with a back design of two porcelain vases from The Taft Museum in Ohio.  Cel-u-tone finish and the sliding original box, as well as the cards, are in very good condition given that they are over 50 years old!

The World of Congress Playing Cards was first produced in 1891 by Russell & Morgan Company and is considered the finest and most expensive brand of playing cards with decks of lavish backs, gold or silver edges, telescope cases, and back designs that reproduce the most artistic paintings.

Both decks are clean, with no dog-eared edges, creases, stains, rips/tears, etc.  The back art design is also in very good condition.

For the collector of vintage playing cards!
