No need to thank me I think is a service to our memebership to make them aware of these opportunities. Another very valuable rol these prints play is to teach us how a well exposed well printed piece should look like.
When I was learning how to print in pt/pd I took apart the frame from one of the prints I had purchased and looked closely at how it was printed, the texture of the paper, the step tablet densities, etc. It was invaluable help.
I remember thinking I was a pretty hot darkroom printer, and then I went and saw a show with Paul Caponigro prints, well that disabused me of my beleif right there, I knew I had plenty more to learn. So the ability to have an original print made by some one with many years of experience I think is an excellent learning tool.
