The presented object appears to be an offset print fixed to a round wooden plate with unknown measurements. The print was made after a Greek icon depicting St. George fighting the dragon. This piece was made in the second half of the 20th century.
This piece is in medium condition and there is no serious damage visible in the images provided.
A fair market estimation would be between 5 to 20 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,
