This is a vintage 1973 press release from the ABC Television Network's Press Relations department, issued from their corporate headquarters at 1330 Avenue of the Americas in New York City. Dated April 9, 1973, this last-minute program correction notice was distributed to television stations and media outlets to update the broadcast schedule for Saturday, April 28. The document formally retracts the previously announced film "Oliver Twist and the Artful Dodger, Part I" and substitutes the Hanna-Barbera animated special "Yogi's Ark Lark" in the 9:30 AM EST timeslot on *The Saturday Superstar Movie* anthology series. The notice provides detailed production context, describing the program as an original animated comedy-adventure made for children, featuring forty of Hanna-Barbera's iconic characters, including Huckleberry Hound, Quick Draw McGraw, Top Cat, Snagglepuss, and Baba Looey. It also notes the plot, in which Yogi Bear and the inhabitants of Jellystone National Park seek a new home due to pollution, reflecting the era's burgeoning environmental consciousness, and includes the original air date (OAD) of September 16, 1972. Printed on distinctive goldenrod stock, this piece of broadcast ephemera exemplifies the pre-digital logistical communication of a major television network. The header prominently features the classic lowercase "abc" logo and the cautionary instruction for stations to check local logs, a standard practice before centralized electronic scheduling. The document's single horizontal fold indicates it was likely mailed in a standard business envelope as part of a weekly press packet. For collectors of media history, animation memorabilia, or mid-century advertising, this press release serves as a tangible artifact documenting a specific programming change for a significant Hanna-Barbera production that later spawned the series *Yogi's Gang*. It captures a moment in the lifecycle of a network television schedule and the behind-the-scenes administrative work required to manage it, offering a direct link to the broadcast culture of the early 1970s.
