Unusual vintage advertisement/solicitation mailer/letter from the Northeastern Dental Laboratory in Detroit, Michigan, signed by Harry O. Solomon, Dental Technician. This postage-paid letter was sent to dentists advertising the experience, services, knowledge and workmanship of the technicians at this dental laboratory. The front of the letter features the beautiful fortress-abbey of Mont St. Michel in Normandy, France, along with a brief write-up about the area. This vintage collectible is in good, clean and undamaged condition with no rips and minimal age discoloration. It measures 10-3/8" x 6-1/2" and would be a great piece for framing! It has been stored in a protective sleeve and will be mailed in a bubble envelope with cardboard to keep it flat in transit. Smoke-free environment.
