Dear Jose,

Thank you for contacting Mearto with your appraisal inquiry.

The presented object appears to be a serigraph print with unknown measurements. The painting depicts two men with hats and makeup. This artwork was made and signed with a felt tip pen by the fashion illustrator Antonio Lopez (1943-1987).

Comparable objects were recently offered and sold on the international auction market. 
This piece is in good condition and there is no serious damage visible in the images provided.
A fair market estimation would be between 200 to 400 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
