An old Trailway's bus photograph taken at an unknown location. Circa 1960's?

 

I found this classic Trailway's Bus Company photograph at my link page Northern California Bus Fans, which is located to the right of your computer screen at www.norcalbusfans.com

 

Photographer Jerry Squire, took this photograph many years ago, but no location, description or year is given. Judging by the cars to the right of the photograph, the bus color scheme on this 1960's era General Motors motorcoach, and the way the people to the left are dressed, I am willing to say that this photograph may have been taken during the late 1960's.
