 Hi. Thanks for your note. I've dropped the picture you were unsure about and loaded up a different one. What is the rule regarding anonymous old postcards in which there was no claim or assertion of copyright? I took some information from the Library of Congress Prints and Photographs Reading Room. I found this information useful:  

 :To establish a prima facie case of copyright infringement, the plaintiff must prove "ownership" of copyrighted material and "copying" by the defendant. (Norma Ribbon & Trimming, Inc. v. Little, 51 F.3d 45, 47 (5th Cir. 1995) (citing Lakedreams v. Taylor, 932 F.2d 1103, 1107 (5th Cir.1991). A plaintiff establishes "ownership" by demonstrating that the material is "copyrightable" and that he complied with the statutory requirements in securing the copyright. Central Point Software, Inc. v. Nugent, 903 F.Supp. 1057, 1057 (E.D. Tex. I995).  

 :If it is difficult for you to find a rights holder after employing due diligence, it ought to be equally difficult for a claimant to show that a copyright had been secured. 

 I take that to mean that if an image is unmarked and unclaimed and has been in the public domain for some years (a postcard for example) then it would be hard for anyone to claim copyright infringement.
