A third publisher of “Australian Edition” comic books was Atlas. The comics Atlas published came out later than those put out by Tip-Top and Thriller, and they seem to be better organized — the comics run in sequence without the randomness that occurred in some Tip-Top titles.
The comics may run in sequence but the material in No. 13 (April 11–August 22, 1954) is older than that which is found in No. 14 (November 8, 1953–March 28, 1954). I found these titles on an eBay and was fortunate to win the lot of them for less than $20.00. They were listed by a seller in Australia, and don’t turn up very often — maybe once a year.
