It might be that although the negative or existing prints are out of copyright the owner of a photograph can make a new print and hold copyright on that.

Many art galleries don't allow photography. That way they can photograph their Rembrandt, or whatever, have copyright in the photo and charge for it what the market will stand.

Unless they already have a deal with Getty Images is there anything to stop EFDSS selling prints for less and using the income for it's (and our) own benefit?
