OK, a friend recalls reading a hardback book on handwriting analysis/graphology when in high school. This would have been around 1993. It was written by a male author & had a simple title like GRAPHOLOGY or HANDWRITING ANALYSIS. She said it was the most thorough treatment on it she’s ever read, and the writing style seems to have put it from the 1940s to the 1960s. I’ve gotten all the listings I can on Amazon. I’ll run them past her when I get the chance. But I am wondering if this brings anything to mind.
