This is a 1960 Massachusetts FALL INSPECTION Sticker. They were issued from October, 1960 to April 1961.
These are "peel and stick" stickers BETTER than the originals and they attach to the inside passenger side of the windshield.
NOTE: This is NOT the only sticker you need to make your classic 1960 car correct. In 1960 there were no license plates issued so you need also the 1960 Registration sticker to verify the car was legally registered in 1960, See our REGISTRATION STICKER for 1960.
