This is one of the most-photographed and recognized helicopters in the world: “Marine One” is the official government helicopter of the President of the United States. This LEGO model mimics the profile, colors and markings of this famous Marine helicopter whose mission is to transport the President. In standard production this helicopter would be known as the Sikorsky S-61A 'Seaguard.'
This is also a model I have built and sold on the Internet. The model has 250+ pieces and measures about 12 inches long (nose to tail), 4.5 inches tall, and has about a 14 inch main rotor diameter. The model features free-wheeling main rotor, tail rotor, wheels, and cabin doors portside that open. It is the first where I experimented with creating custom decals to apply, including the US flag and the official seal of the President (placed below pilots' side windows). The first picture of the built model includes a wallet-sized photo of the actual helicopter, placed in front of the model's tail rotor.
