Vintage Painting shops on Board - Amateur Cubist Modernist Red and Green Modern Still Life

shops This cool old painting
is rendered on a canvas board
made by the National Card, Mat and Board Company
of Chicago/Los Angeles.
It looks to be from the 1940s or 50s.

The painting is bright
but worn on the corners

It has a critique of some kind written in pencil on the back
and the title of the work, Still Life #7
I can't make out the artists name in the upper left corner of the back.

This is a 18 x 24 inch painting
and has a great look to it.
