Vintage Modernist /psychedelic Original Oil

Vintage Modernist /Psychedelic Original Oil Painting Signed Zesiger/ Dated 1969. I picked up this particular painting a while back from an estate sale, and it was unframed when I found it. I had it professionally framed, and it looks amazing! I was not able to find any information on the artist, but the work speaks for itself, and it has tremendous colors. The painting is oil on canvas and is signed and dated in the lower right hand corner of the front. It is in good condition and the only minor floor that I can see is it has some stretcher bar marks around the edges. It measures approximately 15 1/2 x 17 1/2“ framed, and the viewable image size is approximately 8 1/2 x 10“. Thanks for your interest..
