I have a brass Princess Mary tin, which is a lovely thing to own. It was inside a locked wooden box belonging to my father-in-law, with a handful of other precious things - photos of his mother, telegrams etc. I don't know who it belonged to. It is possible that it may have been picked up in a junk shop for a few pounds, but given where it was located and the other contents found within, I think it has sentimental value. There are a lot of Princess Mary tins in circulation - there are hundreds for sale on eBay. They were intended to be distributed on Christmas Day 1914 to soldiers and sailors of the British armed forces, and I think contained tobacco, sweets and so on. Dad-in-law (John Frederick) was born into a farming family in 1922. His father didn't serve in the Great War and neither did his paternal uncle; they both stayed working on the farm. On his mother's side, one uncle served with the Australian army, having emigrated just before the war. The other uncles remained working on the farm apart from one, Fred, who was called up under the Derby Scheme in 1917 and killed in action right at the end of the war. My father-in-law's mother was close to this particular brother and named Next of Kin on his army records. Given that the box also contains postcards and Christmas cards to his sister in Flanders, I would have thought that the tin was Fred's - but, he didn't get called up until 1917. Was it just 1914, or were such tins given out every Christmas?
