The Time Machine by HG Wells.
Airmont Classics series paperback N Y 1964.
Interesting cover art by an anonymous artist envisaging a time machine as a type of flying oven. From the portentous introduction by Donald Wollheim:
'..if you have never read The Time Machine before I envy you the experience. It is a fascinating story you have awaiting you, one that spans all time until the last red rays of a dying sun shine down on a bleak and used up landscape. A story that will linger in your imagination…
Is it to be this way? you will ask. This is a vision of a future, but is it to be the future? We live in a pivotal century which may well decide what will happen to our children's children for a hundred generations. So, reader, the decision may well be up to you.'
