Dr. Lynas' "Maple=O" Maple Syrup Sign; Vintage Advertising Sign

Vintage 1906, black, NOS, cardboard sign that reads: "Dr. Lynas' Maple=O Makes Excellent Syrup" in yellow lettering. These were found in storage at the old Lynas Products facility in Indiana many years ago. It's in very good shape because it was made with a wax coating which helped in preservation, there is some light aging. Great looking and guaranteed to be old and original. Frame or display as is! An excellent, well-preserved early advertising sign!
