Since everyone was so helpful in giving me print framing and hinging
information (thanks to all!), I thought I'd challenge you with this new
scenario.  While speding Xmas at my future mother-in-law's, we unframed a
lithograph from the late fifties to reframe.  Well, what a mess!  It
turns out that the people who did the frame glued the entire print to the
supporting matboard.  After examination, it looked like they used some
sort of contact paper to fix the drawing (you can see onion-skin-like
paper peeking out from the edges of the print).  Sooooo, what are the
options for removing this print from the matboard and then reframing?
Good luck to all, and thanks.  Jeff
