2 paintings on a herrinbone twill canvas...

...Rembrandt painted 'Lady with a pink' and 'Man with a magnifying glass' both on a canvas with a herringbone pattern.
I found the X-ray images on the RKD website. The original X-ray images are made by Alan Burroughs between 1925 and 1944 and digitalized by NEDCC in 2004.
Imagine if we could make new images with modern technology ,it might be possible to do a thread count and weave a reconstruction...
