In the 1940s, it was Senorita Rio!
In the 1950s, it was UnderCover Girl!
Here's their 1960s counterpart in her final appearance from Charlton's Secret Agent #10 (1967)!
Written by Dave Kaler, who also wrote the Steve Ditko-illustrated Captain Atom series, and illustrated by Jim Aparo, who would become the primary Batman artist of the 1970s and 1980s, this was the last of only three stories about private eye-turned-secret agent Tiffany Sinn.
Interestingly, her first two appearances were in Career Girl Romances!
(Well, being a detective is a career...)
Be here next week, when we present another tale of classic comic grrrl power!
