All 1961 Pontiacs used the same form with the exception of the Tempest/LeMans. This year the assembly plant name was pre-printed right on the form, and in a different font. This is the easiest way to identify one of our (or original) 1961 window stickers from one of the other companies out there making reproduction Pontiac window stickers. Our 1961 window stickers have the pre-printed plant name, correct formatting, and correct font. We pay attention to details.
