Based on this response, Vivian Vance was writing a book in the early 1970’s. Postmarked on February 14, 1974 this postcard sent to a Mr. Michael Marcel, she states – “I am writing my book – Viv and will be unable to grant your request for it’s all in my book.” To our knowledge this project never came to fruition so could there be an undiscovered autobiography somewhere out there?
