Par-T-Pak Beverages lost their fizz several decades ago; even though it's on a north-facing wall, the painted ad in the first photo is very faded.
The second ad looked little better until 2011, when it was one of several to be restored as part of a beautification project for San Francisco's historic, now down-at-the-heels, Tenderloin district. As of my photo, the single-room-occupancy Hotel Warfield had yet to make hay from the makeover; that small sign still reads "vacancy."
