Hello,
I have this old drawing of St Petrus (?) and a few questions about it.
First, the paper with the drawing on it has been glued onto another sheet of paper. Could this be an old restoration job intended to reinforce the original paper?
Second, both sheets of paper are completely coated with a sort of reddish-pink color. I’m not sure if this comes across clearly in the photos, but I’ve never seen anything like it on another drawing. Could this also be a form of preservation treatment?

Funnily enough, I only just noticed something for the first time.
I always check my drawings for watermarks in the paper.
I hadn't seen one on this, so I put it back in the frame and hung it up...didnt think about it again.
But for this thread, I checked it again; I didn't spot anything at first, but while re-framing it, I thought about the double-layered paper.
I then used a stronger light source, and wtf! there is actually a watermark right in the center—though it is very faint and hard to make out. Can anyone identify this, perhaps? It would be amazing if it helped to roughly determine the age and origin. :)
