I've recently started a creative photography mounting and framing hobby.
I own some really nice physical photograph prints of various people and places that I purchased over the years. These include things a nature scene in Wyoming, a photograph of The Bean in Chicago's Millennium Park, and a photograph of Kobe Bryant doing a slam dunk. All the photographs are physical prints that I purchased from the legal owner / licensed printer. I am not doing any actual printing myself here.
As part of my hobby, I like to create frames that fit the photo print and I consider it an extension or addition of/to the art-work that is the printed photograph.
I was recently asked by a neighbor if I would sell one of these works. I let him have it at no cost but this got me thinking -- would it be legal for me to sell (re-sell) these framed prints online? I do not have any right to reproduce the images, but I do own the prints.
I live in the USA so USA law should apply.
Please keep in mind, the mounting and framing I do is substantial and inseparable from the original item. I consider it to be a new, greater piece of art. It is no longer the same piece when I resell it.
