I would like to thank U S Television Office, Inc. (USTO) who gave me
special permission to use the photos of William Boyd as Hopalong
Cassidy, and the name of Hopalong Cassidy in my stories.
USTO is the direct successor to William Boyd Enterprises, who own the
name, character, film, stories, and personal likenesses of the character,
Hopalong Cassidy.
