Space Adventures #3 (1959)

This anthology issue contains three space-themed stories. The first features Rex, D'Arcy, and Speed investigating a mysterious cloud of unknown origin, only to discover it contains exotic plants that put them to sleep—later revealed to be a Venusian attack on Earth. "The Cloudships of Magonia" recounts a legendary tale of cloud-based ships from Magonia that allegedly landed on Earth centuries ago during hail storms, with their crews harvesting crops before departing. "The Time Skipper Travels to Ancient Rome" follows a professor and his companions as they use a time machine to travel back two thousand years, only to become trapped in ancient Rome and must escape before the machine slows down completely.
