Dear John, 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 convolute of 5 serigraphs with 34 x 24 inches measurements. The advertisement posters with the context of Belgium breweries were made in the middle of the 20th century (probably mainly in the 1950s). The named companies are "Horse-Ale Imperial" (Belgium), "Den Hert" (Belgium), Imperial (Belgium), a motor cross race sponsored by Belga (Belgium), and a bicycle race from Brussels over Paris and Reims and ending in Brussels Comparable objects were recently offered and sold on the international auction market. These pieces are in medium condition and no severe damage is visible in the images provided. A fair market estimation would be between 40 to 100 USD each. This estimate is based on recent recorded auction sales of comparable items. Retail "asking prices" can be higher and may vary. With kind regards, George
