This is a 1950 Massachusetts FALL INSPECTION Sticker. It has been restored and reproduced with our patented "Peel and Stick" format. This allows attaching to the lower inside passenger side of your windshield.
They were issued from November, 1949 to April 1950 and they were good for one year.
NOTE: In 1950 Massachusetts did not issue license plates. Instead it issued a registration sticker. If you want your car to be historically correct you need yo go to our 1950 Registration site.
