M-G-M's Lassie #28

In "Trouble on the River," Gerry and Rocky navigate a timber raft down the river toward Santaro, their journey interrupted when Lassie springs into action to rescue passengers from a sudden flood on a riverboat. Among those saved is Senhor Velho, the sawmill owner at Santaro, whose presence adds unexpected weight to the day’s events. Ralph Mayo handles both pencils and inks for the story, while Mo Gollub delivers the cover art for this 1956 Dell comic.
