...covering Australian comics
"Magman Giant/Jumbo 1971-1974 series" is a group of 95 titles with continued numbering.
From December 1965, Magazine Management comics were published as one-shot issues with 'catalog numbers' on the cover, rather than individual titles in sequentially numbered series.
Magman's Giant/Jumbo editons ran through several series restarting at '01' or '001':
There were no comics published with codes for 1977. Magman Giants include a brief series with '11' prefixes that don't fit the overall pattern.
The prefixes provide a guide to the year of publication, although some issues were released late the previous year for sale in the year shown in the prefix.
Magman published distinct runs of catalog numbers for Standard, Top Comics, Pocket 'Picture Stories', Pocket Romance, Giant/Jumbo and Rebound editions.
