Just curious, but when did Sams come into the public domain?
My full disclosure: I once worked for a company that wanted to post Sams excerpts to the web, but the company attorneys let us know that Sams had exercised their extension rights on the original copyrights. Sams would be happy to license the rights for $$, but the bosses balked at that, thinking they had read the copyright rules correctly.
A Google search of the "Catalog of Copyright entries" (a Library of Congress publication) confirms that Sams did extend the copyrights in 1964-1976 for early Photofacts (sets 1 - 198, all I could find). Question is, for how long?
