I purchased this at an estate sale. The individual cards are mounted on the backing so I can't see the backs of them to determine who produced them. I do know there were a limited number of cards produced of the stained glass windows.

Dear Verna, 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 set of lithographic prints with 38 x 24 inches measurements. These prints were made after designs or motifs of the 12 tribes by Marc Chagall in the second half of the 20th century. There is no maker or producer signature of remark visible. Comparable objects were recently offered and sold on the international auction market. This piece is in good condition and no severe damage is visible in the images provided. A fair market estimation would be between 150 to 300 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
