Dear Teri,

Thank you for contacting Mearto with your appraisal inquiry.

The presented object appears to be a painting made in oil or acrylic paint on canvas with unknown measurements. The painting depicts an abstract motif. It is signed with the name Rappaport and dated 1963. This painting could be made by the American artist Ann Rappaport who was active in the 1960s.

Sadly no additional information for an artist with this name fitting in style and motif is given by reference books and databases. 

Comparable objects were recently not offered and sold on the international auction market. 
This piece is in good condition and no severe damage is visible in the images provided.
A fair market estimation would be between 300 to 600 USD.
This estimate is based on actual recent past recorded auction sales of comparable items. Retail "asking prices" can be higher and may vary.

With kind regards, 

George
