Concern for Signs from the Past in Seattle & NYC

Came across an article raising concern for the future of a number of old neon signs in Seattle, such as the old Wonder Bread sign in the Central area which sits atop a bakery scheduled for demolition. Although an offer has been made to save the sign, there is a concern that it may be sold off piecemeal - especially the WB. Other classic signs in Seattle include the Post-Intelligencer newspaper "P-I" and the Elephant Super Car Wash. It is believed that Seattle preserved their neon inspired by the famous sign at the Pike Place Market which dates back to 1907.

In the same newspaper, one can read about an original terra-cotta model T-Ford medallion, circa 1922, at the Tunnel Garage in Manhattan that was uncovered in preparation of the garage 's demolition to make way for an eight-story apartment building. There is a movement afoot in the neighborhood near the Holland Tunnel to save the medallion, even if the building itself cannot be saved.
