Bad idea to start looking through old photos when you should be doing something else but it's a great distraction. One thing links to another in a satisfying manner.
For instance this photo, from the same period as
the ones in the last post - perhaps even taken by Gerardo Guerrieri (he
was always observing, photographing and/or recording everything). I
don't remember what I was painting when this picture was taken but it
must have been a portrait, judging by the gaze focused on
someone....maybe my sister?
