It's John Claude Hamilton again!
Here he is:
It's been brought to our attention that there is some additional writing on the photo at the end of the word 'regards' running diagonally at right angles to it.
OH and I have fiddled with photoshop trying to enhance the writing (which will probably turn out to be someones shopping list imprinted on the image
), but we can't make it clear enough to make out, so wondered if anyone else can?
Here's the corner of the photo scanned at 1200 dpi.
