Vintage rare and original late 1960’s painted Masonite Biohazard sign. This came from the County of Los Angeles Medical Examiners office. I acquired it from a good friend who retired from there after many years. This was in the entrance to the lab before they replaced with new signs in the early 80’s. It measures 24″ x 12″. The back has some discoloring and has a waffled texture. There are a few small age spots where the Masonite has become warped (see pictures).
