The artist for this story, Jack Manning, was completely unknown to me until I stumbled upon this comic in a recent buying binge. Manning, who died in 1986, had an impressive resume of work; drawing funny animal comics for Dell for about 20 years. He also animated for Hanna-Barbera from 1959 to 1967.The Roman Holidays was a short lived Hanna-Barbera cartoon (13 episodes), turned into an even shorter lived comic book from Gold Key (4 issues). Taking a page from both the Flintstones and the Jetsons, The Roman Holidays were a nuclear family set in another time period - in this case Ancient Rome. This comes from The Roman HolidaysNo. 4, November 1973.
