Sorry for the delay today folks. Duty calls.
Anyway, I think this one's a real treat, only because THE BLACK CAT doesn't necessarily pop up when one thinks of pulp magazines.
Galactic Central's summary: "A very off-trail magazine which liked to publish unusual stories and featured a large amount of fantasy in its early years. Authors include Jack London, Octavus Roy Cohen, Ellis Parker Butler, Cleveland Moffett, Harry Stephen Keeler, Frank Lillie Pollock."
BLACK CAT, December 1912.
