I visited Kennedy Space Center in Florida maybe 20yrs ago and went bonkers at their gift shop. Came home with "stuff" galore, along with a large poster showing cutaway view of Columbia. It eventually went with kids to a school show and tell day. I no longer have it. But, you might want to check NASA...they have huge site at
www.NASA.gov You'll be able to spend days there if you like. While there, try and locate a great research paper entitled From Engineering Science to Big Science, the NACA and NASA Collier Trophy Research Project Winners. Most impressive, including old and newer photos.
Also, this past July 17th, many Sunday newspapers in US added a section in tribute to NASA. It coincided with the final space shuttle flight. They are retired and seems interest has now grown in general. Try the following:

Check search engines on your PC snapshot, simply say space shuttle, and many new sites can be explored nowadays. Hope something here helps, good luck and enjoy.
