Hi all,
I am in discussion with a UK museum over the release of an image from their digital collection under more liberal terms than CC BY NC. It is of a portrait made around 1915, of someone who died before 1930. I don't know who the painter was, nor whether or when they died. I don't know who made the photo or whether the portrait is actually in the museum (I suppose it is).
Is the above information sufficient to determine the copyright status of the digital copy?
Thanks for any pointers,
Daniel
