Most of comics were one-shots

A Climax Comic [2] Pirate's Gold: 1947 (KG Murray, Australia).

Jo only lasted a few months in the Daily Mirror, but such was Bertram’s obvious talent that it wasn’t long before the character began appearing in several one-shot comic books published by Sydney’s Frank Johnson Publications, some appearing under the company’s famous ‘Magpie Comic’ imprint. Published during 1945-46, Jo & Her Magic Cape (as the strip was now known) appeared in such titles as Modern Comics [nn] ([1946?]), Dandy Comics [nn] ([1946?]), Fearless Comics [nn] ([1946?]), Triumph Comics [nn] ([1946?]), Universal Comics [nn] ([1945?]), Wizard Comics [nn] ([1946?]) and Wonder Comics [nn] ([1946?]).

The NSW Bookstall one-shot comic, Tokyo's Secret Weapon [nn] ([1944?]), issued in the mid-1940s, features another Jo & Her Magic Cape story. Bertram’s glamourous heroine also appears in Pacific Bandits #C9 ([February 1945?]), a one-shot comic published by Offset Printing Company towards the end of World War Two.

“Most of my comic books published were one-shots. They piled up on the newsagents and my sister and I always got a great kick out of seeing them. I did covers and all.”

If ever an artist’s work deserved to appear in colour, it was Moira Bertram’s. Thankfully, comic book fans got to enjoy several full-colour Bertram comics, which were published in the KG Murray Publishing Company’s groundbreaking A Climax All Australian Comic (KG Murray, 1947?) series, which appeared in 1947-48.

These were:

• Pirate's Gold [nn] ([1947?]) (Climax #2)
• A Climax All Color Comic #5 ([1946?])
• A Climax All Color Comic #7 ([1948?])
• Climax Color Comic #10 ([1948?])
• A Climax Color Comic #11 ([1948?])
• Climax Color Comics #12 ([1948?]).

Climax Color Comics 12: 1948, including Bertram's "Adventure in Siberia" with Captain Buck (KG Murray, Australia).

Bertram’s exaggerated and expressive art style is tailor-made for these gaudy four-colour comics, which are as stunning to behold today, as they no doubt were to the kids who shelled out their sixpence for them in the 1940s.

Aside from A Climax All Australian Comic (KG Murray, 1947?) and her one-shot Flameman Genie of the Sun [nn] ([1946?]), Bertram’s other series for the KG Murray Publishing Company was Miss Career Girl, which appeared as a back-up strip in some issues of Murray’s full-colour Superman All Color Comic (KGM, 1947 series) comic.
