Dear Gloria,

Thank you for contacting Mearto with your appraisal inquiry.

The presented object appears to be a small-sized painting made in oil paint on canvas with unknown measurements. The painting depicts a couple with a guitar player and a dog in the background. It appears to be dated 1939 and signed in the lower right corner by Rene Portocarrero (1912-1985).

Comparable objects were recently offered and sold on the international auction market. 
This piece is in medium condition and there is no severe damage visible in the images provided.
A fair market estimation would be between 15.000 to 30.000 USD.
This estimate is based on actual recent past recorded auction sales of comparable items. Retail "asking prices" can be higher and may vary.

An artwork of such high potential value requires further authentication research. This estimate is provided on the condition of authenticity.

With kind regards, 

George
