Yankees Playing Cards

My Dad was a huge Yankees fan. When he passed I found this deck of cards in his desk. My Mom says he must have bought them before they were married in '51. The box has obviously been opened, but the cards are in the original sealed plastic. I assume the cards are simply normal playing cards with the Yankees logo, and don't have anything fancy like player's photos. Has anyone seen these cards before and know anything about them? e.g. were they sold in shops or at the stadium? What year(s) they were available? I haven't seen them in any Yankee memorabilia sites.
