Each page is 12.75 X 9.5 inches. The paper is 70 lb rough w/c paper made many years ago for Grumbacher. The original sheets were 19 X 25.5 inches. Each sheet is folded twice into a signature and there are five signatures for a total of forty pages. Some will be blank (or wordless) by design of course.Tired of apologizing for the way it is scanned. I need a larger scanner.Where did everybody go? Are you ever coming back?
