Michael Whelan's cover for the 1979 Ballantine-Del Rey paperback of "A Warlord of Mars" featured his loyal companion Woola, a ten-legged Martian dog (calot) loyal to John Carter.

"Warlord of Mars" was also the name of one of the earliest RPGs based on ERB's Martian stories. It was published by Heritage Models Inc. in 1979 and designed for use with a line of metal miniatures.

The 1919 hardcover edition of "Warlord of Mars" by McClurg was J. Allen St. John's first John Carter cover. Between 1918 and the 1940s, he would paint numerous covers and render many interior line drawings for ERB's Martian stories in pulp magazines and hardcovers alike.

ERB's "Warlord of Mars" was the third installment of his Barsoom saga. It was serialized in All-Story Magazine from Dec. 1913 to March 1914. This was the first Barsoom novel to earn a cover on the magazine.

In 1971, Doubleday commissioned Frank Frazetta to paint a cover for a combined volume featuring "Gods of Mars" and "Warlord of Mars," ERB's third Martian novel originally published in 1913/1914. This masterpiece depicts John Carter and Tars Tarkas fighting the four-armed apes of Barsoom.

Gino D'Achille's cover for the 1973 Ballantine paperback edition of "Gods of Mars" did not feature Martian fauna, but focused instead on swordplay across the decks of the great airships of Barsoom.

The cover artist of Gold Key's 1964 comic adaptation of "Gods of Mars" depicted John Carter and Tars Taras battling ferocious banths, the many-legged lions of Barsoom.

An unusual interpretation of the plant men of Barsoom as giant one-eyed trees from a Spanish translation of "Gods of Mars" published in 1947.

With their single eye and mouth-bearing hands, the plant men of Mars inspired many artists who drew "Gods of Mars," including Joe Orlando's cover for DC's Weird Worlds #3 (1972), which featured comic adaptations of several ERB stories.

The second Mars novel, "The Gods of Mars," appeared as a five-part serial in All-Story Magazine between January and May 1913. Michael Whelan's cover for the Ballantine-Del Rey paperback in 1979 depicts John Carter and Tars Tarkas battling the hideous blue-skinned plant men.

When Penguin Classics published "A Princess of Mars" in 2007, they selected an illustration by David Cochrum and Rudy Nebres that had originally appeared as the cover for issue 11 of the Marvel comics series "John Carter of Mars."

Gino D'Achille's cover for the Ballantine paperback edition of "A Princess of Mars" (1977) was less voluptuous and sensual than Frazetta's or Whelan's, but he captured the bleakness of Barsoom and sinewy strength of the Tharks.

I grew up reading the Del Rey paperbacks of ERB's Martian Tales with evocative covers by the great Michael Whelan. His rendering of "A Princess from Mars" (1985) remains a favorite of mine.

ERB's story "Under the Moons of Mars" was serialized monthly in All-Story Magazine from February to July 1912 and soon thereafter published as a novel entitled "A Princess of Mars." Frank Frazetta made this stunning painting for a paperback edition published by Ace in 1970.
