AC spark plug advertising

Here are some large AC spark plug/AC filter advertising from the early 60's.
There are 32 different layouts for many different gas stations,Shell Mobil,Pure,Conoco,Fina,Texaco,Champlain,Cities Service,etc.
Basicly this would be the display ad's given to each particular brand for the stated year,and each page of this binder is just a photo of the actual items that they would send you(if you notice in the 1st pic,the AC sparkplug with the flame around it ,has double faced tape squares on it,because that's how that would be sent...get it?)
I bought these recently at an antique mall
