Mini Dealer Signs

[Mr70]

I have an entire collection of all of these original GM Desk Sign displays,BUICK-OLDSMOBILE-CHEVROLET-PONTIAC-CADILLAC-TRUCKS,as well as their original catalog ordering info Literature.
The REALLY large outdoor 50' lot signs became a GM corporate staple beginning in 1970,these smaller displays were produced and offered to Dealers to display on their Desks in their showrooms.
There are a few selling cardboard copies on eBay and do describe them as such.
Others are selling plastic knockoffs that are crudely made & sadly lacking in detail.They have many giveaways in their ads that scream "I'm Homemade".
I guess this is the norm when the originals become scarce,but they need to be more honest in their descriptions & pictures,as I've already been contacted by many buyers after they receive them,thinking they were 50 years old & they aren't.
