Dear Jesus,

Thank you for contacting Mearto with your appraisal inquiry. My sincere apologies for the delay with the appraisal.

The presented object appears to be a serigraph print on paper with the measurements of 14 x 12 inches. The print depicts an illustration of Isaiah 11:6-7 and was made by Gino Piccoli. 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 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 20 to 40 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
