Felicity was trained (to paint in oils) by her grandfather: Veikko Malinen, founder of the Finnish Art Society in Kotka, Finland.
Her mother Marja-Leena Malienen was an entomologist, and retired to become a full-time artist, painting predominantly land and seascapes.
In 2008 Mason held a one night only art exhibition titled "The Election Show"[15] at a private venue in Soho, NYC.
