Dear Joanne,

Thank you for contacting Mearto with your appraisal inquiry.

The presented object appears to be a framed print on paper with the measurements of 12 1/2" x 19 1/2". It is the sonett or poem by the French poet Christophe Plantin with the title "Le Bonheur de Monde" from 1570. This print was made or published by the Musee Plantin as we can see on the stamp on the paper. It was made in the 20th century and dedicated as a wedding gift in the year 1936.
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,
Georg
