A stunning piece of vintage industrial history and nostalgia. 
I have had these before, however I don’t often get them with the numbers. These are numbered  51-100. No.1 of the two has slight damage to numbers 64,65 & 66 otherwise all intact and really very decorative. 
 
This lovely piece would have been hung on the wall beside a clocking in/out machine in a work place, possibly a factory or a shop.
 
These are particularly nice having the wooden frame around the slots and unusual with two rows of slots. 
Great to display cards and photos.
