From Beyond the Unknown #12

From Beyond the Unknown #12 (On Sale: June 22, 1971), has a cover by Joe Kubert. This is another book that actually got smaller with the page expansion.

We begin with our cover story, "The Dawn-World Menace" by Gardner Fox, Carmine Infantino, and Joe Giella and reprinted from Strange Adventures #147 (1962). A time-space warp brings two savage cavemen riding pterodactyls into the present day.

Next up is "Mystery of the Runaway Meteor" by John Broome and Sy Barry and reprinted from Mystery in Space #27 (1955).

That is followed by "Earth for Sale" by France Herron, Carmine Infantino, and Bernard Sachs and reprinted from Strange Adventures #89 (1958).

Next, we have "The Sign Language of Space" by Otto Binder, Sid Greene, and Joe Giella and reprinted from Strange Adventures #63 (1955).

We end with  "Gateways to the Stars" by Gardner Fox and Sid Greene and reprinted from Mystery in Space #78 (1962).

Edited by Julius Schwartz.
