Who is this strange man and what has he done with the real Superman ?

I mention UK Annuals more often than the comics they are based on for the simple reason that the durable books have survived in greater numbers than the weeklies …at least in this household. Atlas UK Superman Annuals are often advertised for sale (although at increasingly silly prices). Atlas UK Batman Annuals from the early 1960s seem to be the rarest as he then had yet to become a household name. The flimsy sixpenny Superman/Superboy/Batman/SuperAdventure Australian weekly black and white reprint comics are getting quite rare in the UK now. I’ve saved perhaps two dozen for the simple fact that when I was a teenaged comic trader I never sold them because I couldn’t find anyone who collected them. Although I have 30 or 40 Dandy Annuals, some going back to the early 1950s when it was called The Dandy Monster Comic, I know for a fact that I only own precisely 6 Dandy Comics as I’ve just kept one representitive issue from each of the last six decades !!
