I often use picture frames found in charity/junk shops for my artwork; the frames usually having an image already in them which I remove and put to one side. Sometimes behind the displayed picture there will be other stuff that has been covered up - another image, bits of card, paper, dirt, etc... This vicar was found betwixt a watercolour and wood panel. The text on the photo reads 'H. M. Viale(?) & Co, Bristol' and on the back, in ink, 'Southville, Bristol'.
Since digital photography has come along and storing vast quantities of images on your computer has negated the need to print an image, I seldom chance upon the found photo anymore; it's become a very rare event indeed. My only joy now is stumbling across a photograph in a charity shop or flea market - but only if I find one where there shouldn't normally be one. For instance, this photo was found in a box of random paperwork whilst I was looking for knitting patterns in a charity shop in Weston-super-Mare. My golden rule is to never consciously search for them: they have to find me.
Given to me by my friend Mole Leigh back when we were studying in Weston-super-Mare. It was originally framed and she found it in a charity shop - someone once had this picture on their wall. I had it on my wall for a while too...
