The most famous Western movie star of all time...
....in a tale from Toby Publishing's John Wayne Adventure Comics #3 (1950), illustrated by a pair of legendary artists; Al Williamson and Frank Frazetta!
Stars like Buster Crabbe and John Wayne also had comics which primarily ran Western tales, but also did stories based on the other genres they appeared in.
In the case of The Duke, his title also had WWII and high adventure stories.
Interestingly, all the stories featured John Wayne as John Wayne, not as a character like Rooster Cogburn or Ethan Edwards!
