An interesting ad for a variety of reasons. Jazzbo Jim, one can assume, was a minstrelly fellow, probably a caricature with puffy lips and wide eyes. That sort of thing happened in the "good old days" of the "jazz age." The Baker Arcade still exists in the Baker building, of course. This light set was made by American Mazda, a name people associate with cars. But in the 20s it was a brand name for lightbulbs; many of the beloved Maxfield Parrish paintings were originally Mazda ads. Finally: these lights are just a dollar cheaper than the 100 light set you could buy in 2000 at Target. Progress!
