Thanks folks, and thanks Alan for your enlightening email to tell me. It wasn't until an hour after you congratulated me that I got my complimentary copy through the door and saw my pictures there for the first time.
I can't believe two magazines have published my images in the last few month: Amateur Photographer a couple of months ago and now B&W Magazine. I'd forgotten I'd sent them because they have had them so long. It has taken more than thirty years to have been discovered.
It will probably be another thirty years before my next published image appears. Blimey! I will be 97 years of age by then. Still, the prizes always come in handy no matter how old one is.
