I was totally intrigued and the postcard was exchanged for smallish note of British currency and it came home with me. It sat on my desk glaring at me every time I reach for a pen from the pen pot on my desk. Now, several months on I still have absolutely no idea what it is all about!
So, if you have any ideas please do leave a comment. In the meantime I have sent a digital copy of it to the Owston (Ouston) One-Name Study registrant.
