A few nice picture framing images I found:
Image by Owen H R
Old Fishing Chart... I have this framed, on my bedroom wall...
Papier mache frame
Image by Kotomi_
I made this long time ago...
The base is corrugated cardboard. Using papier mache technique, I layered small pieces of news paper on it, and finished with black/white copy of medieval manuscript. Then, colours were added little bit and finished with antique coloured coat.
The picture was taken from "Die Minnesinger", one of 1960's German book series "Insel-Bucherei"
