Dear John,

Thank you for contacting Mearto with your appraisal inquiry. The apprised object appears to be a print mounted on a wooden board. This lithograph in colors was made after a print by Norman Rockwell. The letter which appears to be subscribed by Rockwell appears to be a reproduction.
This piece is in not a good condition. The print is painted with a strongly yellowish paint or lacquer and the edges of the print and the letter are artificially stripped out.
An estimation would be between 0 to 20 USD.
This estimation is based on actual recent past recorded auction sales of comparables. Retail "asking prices" can be higher and vary.

With best regards,
Georg
