Chris,


I doubt if the copyright is enforceable given the passage of 87 years, if it was specifically copyrighted, given that it was arguably in the public domain and not engineering drawings and engineering release forms which were never in the public domain. (A quick search of the Library of Congress copyright records did not turn up anything for "Shop Theory, Henry Ford Trade School"). Further Ford Licensing's focus is on activities that seek to profit from Ford's intellectual property, which obviously isn't the case here where you are presumably referring to a limited number of photos or illustrations for educational purposes.
