Big Boss #70

Having crashed in the desert, a dazed June Robbins staggers into a medieval world within a mirage. The Challengers follow to rescue her before the mirage disappears. Captured by knights, the Challengers issue a challenge - a duel with chariots. Despite Sir Rodfold's treachery, the Challengers win, snatch June, and dive out of the city just before it vanishes forever.
