Vintage 1944 California windshield sticker (sometimes called a decal) - great for stamp collectors, too. This one has what look like some older fold indentations on the top corners. We have temporarily covered up some of the serial numbers on the picture to prevent unauthorized copying of the image. The actual sticker still has a complete serial number (this sticker measures 3" by 2-1/2").
This is a New Old Stock sticker, meaning made back in 1944, but never used.
