As you can see, there are two cards missing (jack of spades, four of clubs — it has a modified four of spades instead) and duplicates or even triplicates of other cards. I've no idea why, that's just how they came.
They're very delicate — a corner came off one as I laid it out. They're also about a quarter of the size of today's cards:
My wife said they looked like they came out of a Christmas cracker, and as a result accorded them the same degree of respect. I really like them, though. I'm tempted to get one suit (probably hearts, as they're in the best condition) mouted for display. However, I doubt my wife would let me put it on the wall.
Oh well, what are university offices for?
