Pennsylvania Railroad Wide Playing Cards Power WWII Era

This is a set of old wide playing cards, I believe for Bridge, since the instructions included are for Auction Bridge, from the Pennsylvania Railroad. The motif is Power and it is displayed on the cover of the box and the back of each playing card. These were produced and given out during World War II. There are 54 cards, plus 4 jokers and the instruction card. The cards are in very good condition with what I would call minor play wear. The box has more wear, but is still intact and can hold the cards. The cards are 2.5 by 3.5 inches.
