Yours Truly, Johnny Dollar was a popular detective radio series that aired during the Golden Age of Radio, from 1948 to 1962. Based in Hartford, Connecticut, the show followed the adventures of insurance investigator Johnny Dollar as he solved cases for his clients. The distinctive feature of the show was Johnny's itemized expense account, which served as an effective scene transition and gave listeners an insight into his daily life.

Throughout its run, Yours Truly, Johnny Dollar featured multiple actors in the titular role, but Bob Bailey and Mandel Kramer were among the most popular. Jack Johnstone was the primary writer for the show, producing approximately 350 episodes, sometimes under pen names like Sam Dawson and Jonathan Bundy. The self-referential nature of the show became a unique touch, with characters sometimes recognizing Johnny's voice from the radio.

As the final continuing detective series of the Golden Age, the end of Yours Truly, Johnny Dollar marked the end of an era. The show concluded with the episode "The Tip-Off Matter" on September 30, 1962. Today, it remains a beloved classic that continues to captivate radio drama enthusiasts.
