"The International Space Station Chart is 24""x36"". This is a truly incredible poster. The main image is being modeled on a CAD (computer aided design) program to create a 3-dimensionsal model. It may later be repositioned for other things. The above shows the current state of the model. A great of detailing is now being added. At left and at the bottom, photos and captions explain how the space station is being built."
