Reply to Kari's Post: I have fully checked all search engines. The link you posted does no help, if you had bothered to read the search results there are NO hits for a painting actually signed by A.Grun. It is simply the words taken apart with results that have nothing to do with my question.
I gave the artists name and the date and I expected an expert to answer.
I'm glad I only volunteered $5... a waste of money I'm sure I can't get back.
