Unfortunately, we had a disaster at the house. During a cold winter while we were renovating, I stored my books and work in a room where a radiator eventually burst. It took a few days before I noticed the frozen steam on the windows. The steam destroyed many of the drawings. What I could rescue I did. I had a few behind glass that I need to photograph.
The drawings are very light to begin with, still I need to do better than point-and-shoot.
