I just found a chair that appears to be a replica of the Eames Lounge Chair made by Henry Miller. On the bottom are the words RD.1975 Frank Doerner. I found it in Chicago. Can you tell me more about Frank Doerner? I know it might be a common name, but a google search comes up with his name and the heritage society in Waterloo, Ontario Canada.
The rest of the chair reads, Northfield Metal Production Company, Waterloo.
