FLYING INTO THE FUTURE
Cartoonist's Commentary:
The above Hanna-Barbera toon reference isn't the only time during the late '60s or early '70s that any writer or artist would mention The Jetsons (1961) and its motif of flying cars, but it was certainly one of the earliest.
About 30 years later for a comedy feature on The Tonight Show, film director Kevin Smith produced a short subject called The Flying Car, using the same flying car and Jetsons reference.
Thanks for the callback, Kev - even though it was three decades later!
