Here is Book # 3 from Francis Terrill (we all know Francis was a she). This is "Hemingray Insulators Priced". This particular copy belonged to Mike Oveson (Mike was a she also. Her real name was Margaret but best not call her that). The inside jacket has a hand written note to Mike from the author. Along with this early insulator book come an original envelope that the books were mailed in. My guess is that very few of the mailers survived . The flap on the mailer is stuck closed. Neat little set for your insulator library. $10 and I will pay for the shipping. Buy it now for $5
