There's no copyright date anywhere.
There are 2 indicia: on the last inner page and on the inside-back cover.
The first, longer fuller one, has the title "Jungle Comic No. 29", but the second says, wrongly, "Jungle Comic No. 24".
The printer info is different. The last page one says: "Printed by 'Truth' and 'Sportsman' Ltd., corner Kippax and Holt Streets, Sydney."
The inside-back cover says: "Printed by Bridge Printery Pty. Ltd., 117 Reservoir Street, Sydney."
