I use the Public Domain category in all the items that I upload. They are mostly photographs taken by myself or by members of my family that are no longer alive or old postcards mostly from my late father's collection. It is my intention that anyone who wishes to use any of my uploads in another context should be free to do so without recourse to me. It would be nice if the pictures were credited if they are my or my family's photographs but I don't insist upon this - my only objective is to put items that interest me into the public domain for the enjoyment of others who might share my interests.
