Realizing it would be best if The Black Owl was still believed to be fighting crime...
...Army recruit Doug Danville aka Black Owl, passed his costume and equipment to Walt Walters, father of patriotic teen superheroes, Yank & Doodle whom Danville had teamed up with on several occasions, most notably Prize Comics #24, when they, Green Lama, and several other characters, took on the Monster of Frankenstein!
While the writer of this tale from Prize Comics V4#3 aka #39 (1944) is unknown, the artist is Maurice Del Bourgo, a journeyman with credits in every genre at almost every company during the Golden Age.
Once their dad became a superhero, the kids became his sidekicks, but remained Yank & Doodle, instead of renaming themselves something avian to match the Black Owl's motif!(Luckily, their color schemes matched!)
Curiously, the boys didn't realize their father was the Black Owl, despite the fact they had worked with the original!
The Black Owl was framed for murder and jailed in Prize Comics #45, and when their father didn't return home, the duo finally figured out their dad's secret identity.
When Walt was shot and wounded in Prize Comics #64, he retired from active crimefighting, serving as a non-costumed assistant to Yank & Doodle until their series is cancelled several months later.
Note: we never learned what became of Doug Danville after he entered the Army...
Next...Enter The Owl!
