Following on from Robert Muat's comments regarding card no. 1:
According to a former workmate who knew Jacky Watters, the player on the front of the card is not him, and this player is wearing a Motherwell kit. Jacky died in 2012 aged 92.
I decided to do some research and thanks to the help of some members of Steelmen Online, a messageboard for Motherwell fans, it seems the photo is Watters, not Jacky as indicated on the back of the card, but Willie, who was at Motherwell from 1947 to 1951.
Willie Watters is second from the left in the group of players celebrating their League Cup victory in 1950-51.
