Donald, I think I've seen that picture reproduced elsewhere and I'm pretty sure it's genuine: Picasso did have a FED 2. But thankyou for making me look again, because you're absolutely right: there is something "wrong" with it, which I'd never noticed before! Unless I'm very much mistaken, I think his shadow on the wall is actually reversed!
It reminds me of photographs they used to retouch for the press or for reproduction on low quality paper, which often contain all sorts of mistakes. It would be interesting to know the source of this picture.
