In summer 2016, The Emperor Norton Trust launched its digital ARchive of Emperor Norton in the Arts (ARENA) with 40-some images — including an intriguing illustration featuring Emperor Norton that appeared to be an early engraving created during the Emperor's lifetime.

The illustration appears in the 1964 book The Forgotten Characters of San Francisco. But, apart from a credit to Robert Grannis Cowan — the son of Robert Ernest Cowan (1862–1942), whose title essay anchors the book, and also apparently (the younger Cowan) the private owner of the illustration who gave permission for it to be reproduced — the book provides no details about the artist, original source, or provenance of the illustration.

For the last nine years, this has been the extent of our knowledge about this work. 

A few weeks ago, seeking intelligence about an elusive cabinet card of Emperor Norton, I requested from the Society of California Pioneers some catalog information about the Emperor-related items in the organization’s collection.

Included in the information the Society sent to me was an unbidden clue about the enigmatic illustration — a clue that has enabled me to solve the mystery and, in the process, crack a window into the the elusive history of one of San Francisco’s most influential early engravers and one of the city’s earliest satirical magazines.
