I've just had a look at that on ebay, incredibly sad the family evidently had no interest in the personal items.
However, I work for auctioneers and at our last sale, the entire contents of a local farm, that had been in the family for generations, there were several boxes full of school reports from the 1920s, photos, letters, certificates etc. but the deceased had never married, nor had any of his brothers (he had no sisters) the farm and all his money was left to distant relations and so no-one was interested in them. They all went to dealers in ephemera.
I would love to put a bid in on that box!
