| Description | Have now sent the dispaly unit to the Smithsonian, where it will soon be used. In addition they have one in Paris at the Palais de la Decouverte, one in Houston, M.S.C., and one is going to the Space Museum at Cape Kennedy. They would therefore very much welcome more of the Vectographs, as they originally discussed (except for the addition of Number 13). Are they still being made? All he can do is assure him that they would be put to excellent use, adnt that they are a great success everywhere where they have been shown. |
