Cave Girl had four issues of jungle adventures (#11–14), and the last one had a strange machine that made dead people come to life by sending them into their own past, but keeping them in the present moment. In the end, the machine sends itself into the far past and disappears from the present.
Men in strange garb appear. It seems that they unfasten the machine and take it away. Actually they are setting up the machine, but since time is running backwards—so do they!
