I'm looking for information regarding a picture I saw once. It was a smallish 10x12 (?) Pastels. It pictured an old woman who has falolen asleep sitting in a rocker/rattan chair, knitting in a basket at the side of the chair. Cat snoozin on the window sill. She is old and grey, glasses perched on nose. Superimposed is a ghost (angel?) of a young girl, dressed in a white dress, long hair down to the waist, with a blue ribbon. The dress is of the "gibson girl" era. The ghost/angel is holding out her hand to the old lady as she sleeps. It's not Peterson, or Lumbers.
Any one have any ideas?
