I have to confess that I have no real idea whether this represents a
"normal" amount of compensation for the artist, but it certainly SOUNDS to
me like they are making a fair and even generous offer. A lithograph will
always look like a print rather than a painting, but I think if it's
well-printed it can be quite beautiful. I'd certainly be happy to take such
an offer myself.
