My GB/CA/1941 pencil drawing

From the paper that I drew this on, and from the general date of all the pages in this folder, the GB/CA/1941 design (my current designation) must have been drawn in the latter 1980's. I just photographed the page, as I like the drawing quite a bit:

For whatever reason, I like freehand drawings, as the overall "look" is superior to drawings that I have done with ruled lines. That means that they are "imprecise", which I can accept.
