Betty Windsor's Flying Circus.
In 1956 you had to go and do your National Service for two years in one of the armed services. I really didn't fancy being told I was to be a Pongo in the Army or spend two years looking at the ocean as a sailor. As I fancied Mrs. Queen letting me play with her aircraft (she had quite a few then.) I thought I'd join them for three years and get a bit of extra pay.
I think the picture shows sort of thing that seem to happen to me regularly, over the twelve years I ended up doing in the RAF. I'm on parade and normally it is tallest to the left shortest to the right. So on this one, they stuck me on the end to look like a right Burk!
Still they do say, if you can't take a joke, you shouldn't have joined.
