K. G. Murray of Australia produced monthly black and white reprints of some DC Comics throughout the 1950s. The main titles were “Superman”, “Superboy”, “Batman” and “Superadventure”. These reprint comics were reprinted for UK consumption both as monthly editons and also hardbacked 160 page Xmas Annuals. These Annuals were published by a company called “Atlas” in the UK with no connection at all to the Atlas/Timely (later to be Marvel Comics) of the USA.
The Superboy Annuals were available for approximately 14 years, from 1953 to about 1967. Along with Superboy stories there were always Rex the Wonder Dog and Detective Chimp stories. Even in the mid 1960s kids in the UK could read about the adventures of Rex the Wonder Dog and the Detective Chimp when they would have already become distant memories in the States.
