In the late 1930s, Moore became involved in the art restoration trade that his father had conducted for 60 years. His father had been involved in the framing and reconditioning of White House paintings since the Grant administration. For Moore, art restoration gradually evolved into a full-time pursuit with him repainting and touching up originals by artists including
Rembrandt,
Velasquez,
Gainsborough and
van Dyck. In 1958, Moore was considered a notable tourist attraction while restoring
The Embarkation of the Pilgrims by
Robert Weir, a painting which covered a major portion of the
United States Capitol rotunda. After his wife's passing in the 1950s, Moore relocated to
Sarasota, where he continued to work until his death on November 1, 1974. ==Work in notable collections==
