- Synopsis
- To try to catch the great, wild stallion was to invite death and disaster, until Hopalong and Topper came to solve the secret behind the stallion.
Certa is credited on Hopalong Cassidy by Jerry Bails' Who's Who. The bony faces with mustache, and hats and movements are all typical of Certa. Very similar to many of his Durango Kid stories.
