From the Santa Fe New Mexican:
July 1, 1964: The city building inspector’s office has completed a sign survey on two streets in the city’s Historical Zone and come up with more than 30 non-conforming signs. So far, only San Francisco and Water Streets have been inspected. All streets within the “H Zone” will be inspected. Any non-conforming signs will have to come down after Oct. 15. Additional copies of the Historical Zone sign ordinance are being printed and will be available from Mel Hagman, building inspector, or the Santa Fe city clerk.
