February 14, 1950: The original Mystic Bridge decal cost 50 cents and was good indefinitely. Without the decal, it cost a motorist a 15-cent toll every time the bridge was crossed. With a decal the toll was only 10 cents. The decal was stuck on the outside of the windshield, moistened and pulled off leaving the imprint on the glass. Each had a number and the decal came in two sizes. One three inches in diameter went on the right of the rear window. A smaller one could be placed on the right ventilator window.
