SPACE SHIP POP POP FLYING SAUCER BOAT - KT - JAPAN

Tin lithographed space ship designed to float on water. The saucer is candle powered using the old pop pop boat technique of heating a metal tube. KT is probably Komatsudo. The very small saucer comes in a boxed version with a real compass and in a bagged header card version with a litho compass. It was later released as in a plain bagged version as a generic "Pop Pop Boat"
