The Adventures of Rex the Wonder Dog #10

In "Secret of the Lost River!", Rex the Wonder Dog and his young friend Danny find themselves in a wild adventure when their cranky uncle leaves them behind to prospect in the remote Painted Mountains. With a killer tiger on the loose and the uncle in danger, Rex must use his wits and courage to set a trap, save his friend, and signal for help—all before the mountain shadows grow too deep. Written by John Broome and brought to life with dynamic art by Gil Kane (pencils) and Bernard Sachs (inks), this 1953 DC classic features a thrilling cover by Gil Kane and Frank Giacoia.
