It's also going to be easy because I'm not going to bother putting the covers in any kind of order, other than that in which they were first published.
This is because many long-term readers of this blog'll already know what my favourite is. A strong hint would be that it's got plenty of purple in it, proving the Incredible Hulk was right all along and that, in the world of comics, purple and green really do go together.
This was my first exposure to the Spectre. I can even tell you where I got it; a newsagents near Blackpool Pleasure Beach. It was run by a woman with light hair. I don't know what she was called. But how I thrilled as the cowled crusader melted one villain and reduced another to a skeleton.
Sadly, after this issue, the Spectre was replaced in the comic by Aquaman. Oh the indignity of it all; to be supplanted by a man who's never melted a villain in his life.
