Black Cat (the original one, aka Linda Turner) was given her own title after a 5 year run in Speed Comics beginning in 1941. Debuting in March of '46 she was originally done by the same artist who did her in Speed, i.e. Bob Powell. Powell wasn't too bad, but I've always preferred her later illustrator, Lee Elias who came on the scene just a few issues later. Lee had a better looking Black Cat than Powell, especially in the rendering of her face and legs. Powell rendered a sexier looking bustline, still I liked Lee Elias's version better. In this storyline, her debut issue, she has a look alike gangster gal dressing up in her outfit and committing crimes masquerading as Black Cat. The real Black Cat goes out to investigate this fraud and gets netted by her boyfriend Rick Horne who thinks she is the gangster mob gal. Several good pics of the Rick's unwelcome netting are shown below. Also a pic of the mobster gal in costume being KO'd and out cold on the floor. Black Cat's great appeal to me was her excellent good looks combined with her fighting skills and great vulnerability (she had normal fighting skills, and was often easily overpowered). She's among the best of the golden age superheroines.
