The first problem with the licensing for these images is that you say that they're public domain ("PD") because you created the images.  As long as you did your best to make a faithful reproduction, you have no copyright in these images: either you've simply copied a copyrighted image and don't have any right to release it, or you've copied a PD image and don't have any rights to control its usage.  [By the way, don't think that I'm charging you with wrongdoing: I'm trying to say this in the simplest way possible, and "you have no rights" is the way that the copyright law works; it's not an assertion that you should get out of my way, or anything like that.]  Therefore, there's no real evidence that we can use these images.  Are the original photos PD?  While most documents and photos created in the 1940s are copyrighted, it's possible that they're PD, such as if they were published without a copyright notice or if they were published with a copyright notice but their copyright was not renewed.  I'm not an expert on these things; therefore, to get details, you should ask a question at Wikipedia:Media Copyright Questions or Commons:Commons talk:Licensing.  These pages are frequented by those much more familiar with copyright than I am, so they should be able to help you.
