This 1930 California Inspection sticker is most certainly the earliest sticker in California.
It was originally issued as a certificate to be filled out and kept in the glove compartment.
We have modified it only slightly to make it fit a sticker format, attractive for California cars in the 1930's.
You can put your car info on the back.
This sticker is designed with our patented "Peel and Stick" format allowing you to place it on your passenger side windshield INSIDE your car.
