This 4" X 6" print of a Sikorsky S-55 helicopter has a military gray frame that measures 6.5" X 8.5". The S-55 was designed for easy maintenance. The clam shell doors on the nose provided full access to the engine. A complete engine replacement only took about 2 hours. The frame comes with a drywall screw for mounting on a wall and a dowel for displaying on a shelf or desk. Handmade in the US by a Vietnam veteran owned company, it is a unique item for all aviation enthusiasts to display.
