A long, flat-roofed sight-seeing boat crowded with passengers sits on the Green River inside Mammoth Cave National Park. A small flag flies from the boat's roof and a railed landing stage is moored alongside in the dim cavern setting.
Black-and-white halftone print with white margins; "(over)" at lower right indicates printed text on the reverse.
No postmark, stamp, address, or handwriting — the back is entirely printed advertising copy (boat trip schedule and fares). White border visible on front; glossy halftone print, mid-20th century tourist card.
