I went to a gallery showing today and they had a number of prints of musicians from all different time periods. They were all framed and the process labeled. They were all large prints, over 20 inches, and I really didn't notice a difference from RC or FB paper. There were RC portraits from the 1970's that were side by side to FB and "archival pigment transfer prints" which I think were modern inkjet prints. I didn't see any noticeable difference or degradation of the RC paper, and that was old paper from the 70's. It was labeled as RC, but that was the only visible difference, at least to me.
