Being new to the forum, I am soaking in as much knowledge as I can hold. I need some help to determine the best way to conservtion frame a signed/numbered serigraph from 1969 that is printed on a canvas background and unstretched. The print is of considerable value, and I want to use conservation materials to mount the canvas and frame with matting and UV protection. I don't want to stretch the canvas, as the print is to remain as original as possible, and have seen one of these prints damaged in the past from being stretched. The image is rather large (24" x 48"). What would the recommend method be to hinge the canvas, and attach it to an acid free backing? Does anyone have another mounting method I could use that protects the print? Thanks!
