I'm about to have my first public showing(!) and of course would be pleased to sell something (although the show in itself is a treat). A friend tells me that the value of a print can be enhanced by labeling it a certain way, which would indicate how many copies of the print have been created, and which copy the potential buyer is actually looking at. Is this actually a significant factor?--because I'm not inclined to disassemble 14 frames for this purpose if it's not that important. If it is worth doing, then exactly how does one do the labeling?
