Since posting I found a string necklace in folded fabric but I think it is seed pearls. I told my wife to unfold any fabric she finds. The beads in the box are ivory (elephant tusk).
Yesterday I sold this painting of a family pet from 1905 for 30 euros. I was offered 25 but played the "sentimental value" card and got 30. Basically its worth is from how old it is, not the painter.
