Maybe he didn't sign it. Rather it looks like someone skated on it. Can you say "cold pour"? A most unusual CD 145 G.T.P. TEL. CO. Scribble maks all over the skirt and into the dome. I'll post a second shot to show more of the surface. If you collect beehives, this is one you will want to add. If you collect Canadian insulators this is one you will want for your collection. If you collect the unusual this is certainly one to put in the collection. Asking $150 and that will get it shipped anywhere in the U.S. or Canada
