Just think of the value of inheriting prints which don't have endless clones or restrikes from a different hand. Brett was an extraordinary printmaker. I could spot a print of his from clear across a room just by its "glow", so to speak. Of course, at the present time scans have been made of his prints, and high quality press reproductions of certain famous images are generaged in quantity for sale; but that's just a step above what we already had in book reproductions, and none of it constitutes new silver prints. His favorite paper itself - the original version of Seagull G - hasn't been made for a long time; and yes, in his case, it made a real difference.
Speaking of personal lifestyles is a tangent - think of the selfishness of any number of them, like Stieglitz. Someone still has the right to control the visual integrity of their own work. Stieglitz claimed there is only one best print of anything. I once saw an exhibition of those master prints, and they did have a very special personal feel which only Stieglitz himself could have rightly adjudicated.
