Wow this button is such a treasure to add to your collection. Not sure what kind of an insect it depicts...maybe either a Moth, Bee or Butterfly. It is from the Bakelite era and made of Celluloid plastic. It measures approx. 1 1/4 in. long. Condition is excellent. Colors are pink tint over-dyed on wings and black body. I have been told that it is a documented Marion Weeber button.
