the image can be seen at:

http://360.yahoo.com/hdnut

it is what I use as an ID image.
it is two girls--very vivid colors
It is my mothers and we have not been able to find any information on it.
There is no signature or anything we can use to ID it.
there is evidence that it was cut down by some previous owner. and partial writing on the back indicating that it may be one of 851. I can provide other pictures of it.
thank you
