Hello Everyone!
Of course, this is really a colorized original publicity still for the Maverick episode "A State of Siege", which initially aired on ABC-TV on January 1, 1961. The plot has Bart in New Mexico, where he lands smack in the middle of a political siege at his new amigo Don Felipe Archelata's hacienda. Don Felipe is played by Ray Danton. Lisa Gaye also guest stars as Don Felipe's fiancée Soledad Lazarro:
Although it's not acknowledged in the episode credits, "A State of Siege" is based--very loosely--on the Robert Louis Stevenson novella "The Pavillion on the Links", which deals with intrigue in Scotland. According to original Maverick documents in the Kellection, Stevenson's story appeared to be in the public domain in most of the world at the time and Warner Bros. acquired "all rights in the teleplay adaptation without restrictions or obligations."
Please stay tuned for much more about our amigo Jack Kelly in the next TDS! :)
