I have four of these Original Sinclair quick change poster. I found them in a old service station that my husband and I purchased in Mo.
We would like to know more about them and how much they are worth. I have done some research of my own only to come up with dead ends. Apparently these are so rare that no one knows much about them.
Any information would be greatly appreciated.
Thank you.
