Mark: Disclaimer - I'm not a copyright expert but have some information. Mileage may vary - End of disclaimer In your case, it is unlikely that the photo in question was ever registered for copyright. That's an expense that most family portrait photographers never did and don't do now. The reason that that is important is that registration brings on statutory damages for infringement. And they can be substantial. If it was never registered, then the damages must be actual, provable damages. In this case, since all of the principles are dead, proving actual damages will be quite difficult. So, it's a gamble to proceed but not a really big one. Here is a reference to a nonprofessional's understanding of when things get into the public domain at a site from Cornell University. http://copyright.cornell.edu/resources/publicdomain.cfm Hope that helps.

I have an old family photo that I would like to use on a book cover. Trouble is that it was a professionally done photo. There is no one left alive that knows who took it. It was probably taken in the 1940s to very early in the 50s, so it think it may already be public domain. Then again it may not be. The people in the photo passed away in their 70s 25 years ago so the odds are no one would ever say anything, but then again. I don't remember how long it takes to have a photo fall into public domain, and if it isn't is there a current procedure that would allow its use? It's not like I have tons of choices, but there may be some. This one just seems to be the only known photo of the people during their youth. All others show them much later in life. Any copyright experts? Thanks in advance. Mark
