Stratoliner Miniature Airplane 3D Puzzle. Punch card pieces pop out and snap together. Fun, tiny model kit for kids, both big and small! First introduced in 1938, the Stratoliner was the first passenger plane to climb above the 12,000ft ceiling with it's pressurized cabin. This airplane ferried military and civilians throughout a long era in aviation history. Curious to know how these little guys go together? Check out this Youtube link below: https://youtu.be/w-vMT8uDeIw We tried to capture the romance of flight, packed on to this tiny card (not much bigger than a business card). This palm-sized model is a fun kit to build with dozens of parts. The miniature pieces lock neatly together to make this replica from the past. You can choose whether you'd like to get the card alone, or packaged inside the clear display cube. Both make the same model. Tiny pieces will not be appropriate for young children.
