Frank Reade Junior With His New Steam Horse In Search Of An Ancient Mine — Luis Senarens

A young penniless widow has an incredible tale for Frank Reade Junior: her late husband had found the legendary gold mine of Mazatlan, an unimaginable mountain of gold discovered in the Los Pinos Mountains of New Mexico by a lost Spanish expedition in 1592. Sworn to locate the mine and restore the widow's fortunes, Frank will have to contend with the cruel and infamous outlaw Black Plume, iron-fisted ruler of that wilderness.
