anyone know what the policy is for using vintage photos? in particular vintage photos with people. I have acquired a large box of family photos [+1500]. many of these are from the 1930's - 1950's. most are of my grandmother and grandfather and family members. There are some of my grandparents that I think would make for good vintage style stock. even though my grandparents have passed on [ have been for many years] would I still need a release? if so, why, and what kind of release?
