Abstractly Fabulous

Sometimes a piece from an unknown artist can be even more intriguing to the eye given the mystery behind its maker. An Abstract Expressionist Oil on Masonite signed Audrey E. Harvey dated 1967 shows great skill with the brush and captures the era with an evocative use of color and style. I welcome input if anyone can shed light on this talented painter, or perhaps the beauty lies in the possible "outsider" appeal.
