As far as I know this is the only mention of WMR being photographed. If you know where the picture is, for heaven’s sake speak up.
This leads me to wonder several things. First, I wonder why they were so keen to get ahold of this picture twenty-seven years after WMR died. Second, I wonder who got in trouble for losing the picture. And third, I wonder whether this is the image produced by the steel plate engraving:
I bought that almost twenty years ago at an antique store and it hadn’t occurred to me until just now that this might be it. It certainly looks to be an engraving.
Bonus: Zoom in on it. Some of it is pretty entertaining.
Sadly, the photo is too low-res to read. Even the enlarged one you get by clicking on it is too hard to read.
Have you given up?
