Hi Jo Anne! Long time! Great to see your name and comment! You always were ( and are) so polite and fun! Re: the murals. A friend of ours was instrumental in keeping the murals intact in CCSF and is still fighting for the murals at UCSF because her Mother was a friend of Diego Rivera, and her grandfather added his paintbrush to some of those in Coit Tower. Guess you can say this family has quite a history with the subject and plenty of reason to see it remain as such.
