Comments by Carrie Lartigue: "I remember her as a tiny little lady of ninety seven years. She and her niece Rhoda Jefferson, attended a meeting the day I joined. I never forgot Mrs. Pinkham's story.. what an inspiration to a beginner!! 'I was reading a book recently, of the life of Thomas Jefferson, when he lived at Monticello. One picture was of the drawing room. It was furnished with a diamond tufted red velvet love seat and chairs. They looked vaguely familiar to me, I knew I had seen them before. Later, I took the book back into my front room... and there was the same love seat and chair! We were so astonished! Rhoda helped me turn the chair upside down, and there stamped on the wood frame was a single word: Monticello.'"
