I came back to add another general theme idea.....
what about photography related things....capture the memories, snapshots of the past, a walk down memory lane, oldies but goodies, everyday moments, this is life, remember the good times, life is not always peaches and creme, etc
and things could be easily based on any color scheme with all kinds of general elements.....we as historians and photographers and memory keepers are ALWAYS documenting the everyday, special occasions, the hard times, the good times, etc.....
