'Are you suggesting it's your perogative to use the labor of others as some sort of entitlement?'
Absolutely not.
I am suggesting that the copyright protection of 'old' photographs is now so extreme that it is preventing photographs of historical interest being published just because the 'author' may not have been dead for long enough and even though there is no prospect of a financial return to the legatees.
I am suggesting that the 'entitlement', which is a relatively modern creation, has, in the case of 'old' photography, got out of hand and is over-riding the public interest.
As an architect for some 50 years, I am well aware of the importance of the rights of artists, including another recent over-reach (at least In Australia) that a published photograph of a building can infringe the architect's copyright!
