Emperor Norton did not possess any royal steeds, but there were a pair of stray dogs who hung out with him at times, and reportedly even dined with him at restaurants (probably not the fine restaurants). Their "tale" is told in Bummer & Lazarus, San Francisco's Famous Dogs, by Malcolm Barker, published in 1984. Item 98. $90.
Item 199 is a broadside announcing Garbage. All householders and persons camping on Public squares or other places, are directed to remove all garbage… This was not directed at leisure campers enjoying their vacations in public campsites. It was published in San Francisco in 1906, shortly after the great earthquake. The notice was put out by the Public Health Commission as it sought to avoid the spread of disease in public parks where people whose homes had been destroyed in the earthquake and ensuing fire camped as they tried to figure out what came next. There are several other such broadside notices published at this time also available in this catalogue. $175.
