The cross-dressing killer
I'm A Cop was a series from Magazine Enterprises (ME) that went three issues in 1954. This is issue #3, entirely illustrated by Bob Powell.
Powell's art looks a little different to me than in either Harvey Comics or ME of the era, where his work appeared frequently. He might have been using different assistants, or at least he approached the job differently. It looks like tracings of photos were used for some of the backgrounds, and each story has silhouetted figures in some of the panels, which is stylistically different than other Powell artwork I've seen.
I like the gritty look of the artwork. The story is more a cop procedural than the usual type of crime comic book. The killer is a cross-dresser; the word "transvestite" isn't used in the story, and the killer, Denim, does make a date with the policewoman. Maybe he's just confused about his identity...?
Feminists will love the panel on page 2 where the caption reads: "She was a policewoman--with a big, fat yearning to play detective, and in my book woman's place is in the home." That reminds me of the Lady Danger stories I've shown. As is typical with those stories, the male chauvinist is shown up by the gal he thinks belongs "in the home."
