Edgar Rice Burroughs Tarzan of the Apes [cent covers]

Published by Top Sellers / Williams Publishing in the UK and printed in Europe, these issues were intended for distribution in Australia (and possibly other countries such as New Zealand). While Australian issue #115 matches UK issue #30 and appears to have been published at about the same time, there is no simple one-to-one correspondence across the whole series.

In the mid-1960s, DC's distribution arm IND bought Thorpe & Porter. In 1967/68, National Periodical Publications (DC) was purchased by Kinney National Company, which merged in 1969 with Warner Bros.-Seven Arts and was renamed Warner Communications, Inc in 1972.

Around 1971/72, Thorpe & Porter's Top Sellers imprint was incorporated into Williams, which became DC’s European publishing division. This was composed of various local companies, such as Danish Williams Forlag, Germany Williams Verlag GmbH, and Williams Nederland B.V. The stylised "W" logo on the covers are a Warner Communications brand.

The Australian versions of Tarzan and Korak, despite the UK publisher, are linked to the series from Classics Nederland N.V. and subsequently Williams Nederland B.V. The Australian edition starts at #115, aligning with the Dutch issue #12115. The series numbering and contents then align with the Dutch version, despite similarities with the UK edition.

While there is no direct alignment with the UK-distributed editions, there are similar sequences of issues at times and a couple of later issues have the UK issue numbers on the bottom of the cover (as secondary numbering). Other Williams editions in Europe are similar, but only the Dutch version appears to match the order, numbering and cover colouring of the Australian distributed edition.
