I am new to the forum and found it while researching an old sign I came across. I have exhausted the normal channels, for example, eBay, WorthPoint and extensive search queries on Google and Bing.
Along the top the sign reads: Garage & Property Owners Association of California.
Along the bottom the sign reads: Quality Service and Square Dealings
It is double-sided.
It appears that someone lettered over the original letting at one point with "Allied Automotive Industries"
Here is what I have been able to ascertain:
The Garage & Property Owners Association was formed circa 1919 in Greater New York by a group of men who wanted to protect and promote the mutual interests of its members, as well as facilitate the permit process.
I do believe this sign came from a garage in San Francisco. Why? My belated friend's father grew up in S.F. in the 1920-30's and he had the sign for many years.
This could be a bit of a gem, as I can not find another surviving example anywhere online, at least, not yet.
Any additional information anyone might be able to provide, as to history or potential value, would be greatly appreciated!
