build your own pentagon cardBuild Your Own Pentagon Postcard

The world's largest office building, with 17 miles of hallways and five concentric rings of offices, was built just before World War II to consolidate the growing War Department in one location. To conserve steel during the war, concrete ramps connected the five floors. The building was in the midst of renovation using more modern materials when it was attacked on September 11, 2001. The new sprinkler system and reinforcements saved many lives. This card includes all pieces and instructions necessary to make a complete paper model at 1:5000 scale, approx. 3.5" wide. It is mailable, with space on the reverse for a stamp, address and a message. Each card also includes a short but informative description of the landmark the model represents. Instructions are included in the form of multi-lingual isometric diagrams.  Build Your Own Chicago and Build Your Own New York series are also available.
