Screen Gems, the distributor for Jonny Quest in the United States, ran a full page ad in The Hollywood Reporter magazine on Oct. 9, 1964, reading

Screen Gems congratulates Hanna-Barbera Productions for creating an exciting new series: Jonny Quest. 7:30 p.m. Fridays ABC Television Network.

This scan of the ad shows Jonny and Race Bannon fighting off the frogmen from the Sept. 18 premiere episode, "Mystery of the Lizard Men."

The next two images are from the collection of a former Hanna-Barbera employee. The first is a photocopy of the bottom of the Hollywood Reporter ad and the second is a mockup for a new poster using the image and some of the type from the original ad. We don't know how old this "new" layout is and we've never seen it reproduced, so we don't know if it was for a project or just personal use.
