Vintage rare and original 1968-69 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 as a forensic pathologist. This was at the entrance to his lab before they replaced with new signs in the early 80’s. It measures 18″ x 12″. The back has some discoloring and has a waffled texture. There are a few small age spots on the front where the Masonite has become warped (see pictures). Sign lays flat and doesn’t have any cracks or breaks. If you have any questions, please feel free to ask. Thank you for looking at my item.
