@Holly:
Wow! Thank you for the info. How do you know all this? It's wonderful! And I thank the rest of you for your advise as well, for they are poorly framed, against glass, and damaged. But I will take them to a frame shop and get them as well cared for as possible. The only thing the lady at the church knew was that they were in an estate and there is an old sticker on the back of each one from a frame shop in Hawaii. The faded out signature could be John Fulton!! but there is an additional name after those two.
Good, they deserve care.
A print is a copy of the original. The original will (usually) be signed. Sometimes the print is also signed by the artist, or it might be signed and numbered. So, let say they have a run of 300 prints. There will be a sig from the artist from the original, then he will do a sig on the print and put 1/300 on the first one; 2/300 on the second and so on. not that i think these prints had a 300 run.
