With these classic covers from Classics Illustrated, we remember H.G. Wells!
The Time Machine
...relating the tale of the author, his travels in time with a machine of his own invention, going forward into danger, and meeting with the Morlocks and the Eloi (as well as friendly native Eloi girl, Weena, whom the narrator of this tale grows quite fond of....) in the future...
....and of the author's final fate!
The Invisible Man
...this story deals with a man named Griffin making himself invisible, then he terrorizes the countryside as the formula that made him invisible slowly drives him mad.
