I stopped into a vendor tent at the mid-coast Maine Lobster Festival in Rocklane, ME, and discovered this insulator at a vendor booth. A local diver was displaying his finds and offering his services. I spotted the insulator. It was a piece he found while diving in Westbrook, ME. A nice bargain for $12.00 given it's an Oakman. Another woman who was selling hand-bound leather products was using CD 134 Stars to lean her items on. I've been going to this festival for over 20 years, and this was the first time anyone there had insulators for any reason (other than myself and a few others in the one-day-only flea market tent that used to be there on opening day).
