Help appraising this large abstract

The building I used to work at has been there since the late ‘50s. Nobody knows anything about this painting or how old it was. They didn’t want it anymore so I gave it a home. It’s signed “Lee Reynolds” and the back is numbered #138756(?).  It has lots of texture and is about 4ft x 3ft.

I’ve read about a Reynolds creating an “affordable art” studio in California around the 1950’s. That’s about all I know. Would appreciate any insight.
