I am posting this for member information.
If you google Peter Proudfoot POW letters, you will note that there are a number for sale as 'fake film and TV props' these have been about for may years and someone continues to reproduce and sell these on eBay as example.
I have recently noted a number of exactly the same letters cropping up in philatelic auctions, clearly fakes, they are a the same letter. Some are carried by larger auction houses who clearly are taking them as genuine.
Buyer beware !!
Hi Peter
Good informative post, I'll highlight this in the Autumn Journal
