I found a couple 1950 articles mentioning a COUGER Oil Co of Twin Falls, drilling wells in Idaho. Also found several other articles from Idaho papers where it is listed as COUGAR Oil Co.
Perhaps there WAS a COUGER Oil Co...??? Is it possible that COUGAR Oil Co was originally COUGER Oil? I have NO idea, I'll leave it to you experts.
I see COUGAR Oil Inc is still around (I assume this is the same company as the old COUGAR Oil Co) and has the same logo, basically, as the sign on ebay...
