Just want to pass along this thought to those of you who ship prints. I sent a 13x19 print to a former colleague last week. I ship prints rolled in 4 inch diameter cardboard tubes sourced from Uline, with a one page note about the print, the paper and directions regarding how to have it matted and framed in an archival manner. In addition to the nice complement about the print from my friend (always welcome!) he said that the framer was also impressed and appreciative of the provided instruction; that this is done too infrequently (this is from someone who has been in the framing business for 25 years).
