Roy Rogers e o Trigger (Suplemento ao Mundo de Aventuras) #4

In "Ataque a Pioneer Landing," Roy Rogers and his faithful horse Trigger find themselves caught in a tense standoff when five impostors posing as soldiers target the payroll aboard the river boat. With the Steamer Captain in danger and the outpost under threat, Roy uses the steamer's whistle to send a Morse code call for help—just as the Sheriff’s arrival looms on the horizon.
