The "Have Gun Will Travel" series, aired by CBS from 1957-1963, follows the adventures of a man calling himself "Paladin." Professional gunfighter Paladin was a West Point graduate who, after the Civil War, settled into San Francisco's Hotel Carlton were he awaits responses to his business card: over the picture of a chess knight "Have Gun, Will Travel ... Wire Paladin, San Francisco." He is a gentleman mercenary who will help people to solve their problems. Though for hire, he will provide his services for free to poor people who need his help. If you needed to hire his services the Hotel Carlton was the headquarters of the man called Paladin!

In San Francisco he lives the high life. He is a successful businessman, wearing custom made suits, consuming fine wine, playing the piano, and attending cultural events. He is an expert chess player, poker player, and swordsman, but when help was needed he changed into the rough riding cowboy who always wore black.

Paladin's primary weapon is a custom-made .45 caliber Colt Cavalry revolver carried in a black leather holster. His holster depicted a platinum chess knight symbol hanging from a black leather gun-belt. He also carried a lever action Marlin rifle strapped to his saddle, and a Remington derringer concealed under his belt.

Dell comics capitalized on Paladin's success and printed several comic books with Richard Boone on the cover. It was also a successful radio series.
