I have taken two more pictures of the signature and the painting itself. The picture of the signature is no better than the last the reason it looks blurry is because the signature is blurry. From the best I can tell the signature goes like this - Ri? iadi maybe Rinniadi, that is as close as I can come. The big R is rather distinctive, and if this was someone famous I'm sure someone would recognize that large R or maybe the D towards the end if in fact it is a D. So here it once again. If you have any ideas that would be great to know.

Maybe it is Riccardi ?
