This is one of the first insulators in my collection. I picked this up near Bowmanville, ON at a barn sale back in 2000 when I had just entered the hobby. I knew absolutely nothing about this but I thought $4 was a fair price so I picked it up. It is embossed only with the "PRISM" symbol and has a neat underpour on the umbrella and some tiny tadpoles in the glass. I found out later this is a bit more rare than I thought. Sorry the photo is not the best quality. I took this a few years ago.
