Very obscure golden age good girl crusader Purple Tigress had just two appearances, in the unnumbered 128 page one shot All Good Comics on November 1944 and again three years later in Jo-Jo Comics #7a on July 1947.  Both books were published by Fox Feature Syndicate.  Both stories are signed under the pseudonym “Betty Brown.”  Grand Comics Database lists the artist in the Jo-Jo version as A. C. (Alvin) Hollingsworth.  It is at least possible he could be behind both stories.
Bails’ Who’s Who suggests he signed work in Fox Feature Syndicate 1944 Everybody’s Comics #[nn] under pen name Alec Hope – this would be around the same time as the first Purple Tigress story. He has art attribution in Fiction House’s Wings as early as 1943, with his largest body of work being on the character Suicide Smith between 1946 and 1950. Hollingsworth started working in the comic industry as young as twelve, and in a later interview he stated “I got my first job [in comics] while I was in junior high school. I couldn’t get paid because I didn’t have working papers.”  Good reason to use a pseudonym.

There is also considerable continuity between the two Purple Tigress stories (including boyfriends and costume – except the purple leopard bikini with purple cape becomes a leopard bikini with purple cape).  Both issues have her pulling a red dress over her head to change into the Purple Tigress.  Despite the length of time between publishing dates the later story might have been previously created and subsequently pulled off the self to fill space as need dictated.

Using the text from both stories, here is what we know about the superheroine Purple Tigress.  Her alter ego is Ann Morgan, who is the “richest girl in the city.” Yet, in her own words, she still “doesn’t know much about business.” Spoiled society girl, she is followed by no less than three faithful boyfriends…Reggie, Henri and Butterball.  As the Purple Tigress she is “a beautiful, cat-like woman,” a “scintillating nemesis of crime.” Beyond this, we have no origin story – no reason behind either her wealth or for her to put her life on the line fighting “The Flasher” and “Thorne’s Gang” jewel thieves.  In that regard, there are no particularly obvious “super powers” except for “cat-like eyes that pierce the darkness” and the ability to quickly change (without the aid of a phone booth) into a cool tiger skin suit and nifty cape.
