I had a few of these already but managed to pick up two regimental examples, one each for the SWB and the RWF. The SWB card is largely plain on the reverse, though the RWF has been used and has a very interesting note on it.
Just a PC from my little dugout in the west. This card is doubly interesting, it is our regiment and it is being sent from the Trenches, of one of the most bloody battlefields in France.
From Dai in France and sent to Deganwy.
I never saw the reverse before I bought it so it was a wonderful surprise to get it and read the message sent.
