On a side note, it's an interesting variation. All 36" versions that I have seen only have neon around the car...
Cause the border normally goes around the can on the 36" versions, so no insulators within the sign like this one
Bryce, pictured is my united motors with insulators & can exactly the same as sign of subject - (Made too be the original single sided version)
I have seen a lot more of the double version with the neon ring around the can with the can being a lot thicker..https://auctions.morphyauctions.com/mobile/LotDetail.aspx?inventoryid=279222
Michael, the 3690. sign is from a 2 year old auction as this sign in auction is part of a 2 sided sign like Bryce mentions with the outer neon ring going around the can so this sign has been slightly altered from its original purpose
(not in its original state) .. ...
