The originals for 526-530 were all Secret Hearts comics; 526 -529 were cira 1961-63 while 530 was a decade later, 1971.
This batch is a five part series. As I was looking through my Secret Hearts covers, I noticed that the "Bad Girl" in many of them was drawn very similar: short dark hair, a condescending and/or triumphant smirk, and body language to match, if shown. All in all a very dominant looking woman. SOOOOO ...
Observe one Robert, a young man on the verge of falling in love with his high school sweetheart, Linda, till he encounters Mistress Carlotta, feminizing dominatrix, in the Vaingirls Zone!
