This treads a line...I know what all the words mean and I'm still not sure what he's selling.
As moonbeam says--is it a photo of a photo? Is it a photocopy printed on glossy paper? Is it a scan printed on glossy paper? Is it a reprint of an actual photo? Is the "facsimilie" signed, or is it a facsimilie of a signed of photo?
A better question I want to know is: Is this seller the original photographer, and if not, does he have written permission from the original photographer to be selling reprints of his work?
Nonetheless, as an ebayer with half a brain, since I have so many unanswered questions, I'd either assume the worst if I were to bid, or just not bid at all.
