I've been working my way through the Haish-related archives at the Joiner History Room, and have come across two unidentified pins that simply read "Haish."
With no additional documentation, one can only make educated guesses about the history of these pins. Perhaps a Haish family member ran for public office? Who knows.
Below are photos of the pins, along with the only identifying information.
