World of All Kinds of Art

I am way out of my league with this sort of thing. We thought about having a verybal appraisal, but the problem we have is that we have no way of transporting this print saftely (It measures 63X47 and it has been professionally framed)

Before we shell out a very large sum of money to have an appraiser come to our home, are there any websites which give more information on verifying the authenticity of art prints? It would make me sick to pay someone $200 to find out that the print is worthless.

Thank you!
