Unique Shell Art Plaster On Canvas Mixed media Lovely Soft Pink Hues Wall Decor

Handmade shell art wall decor probably vintage late 1990's but I can't be sure.  In excellent condition.  Shells, seaweed and rope applied to a painted plaster & paper base stretched on canvas.  Measures about 10" by 12".  No hanging hardware present but would be easy to attach. NOTE in first photo there appears to be a notch in the lower left edge. It's actually where a piece of rope confused my background software, there is no notch.
