'Carved Eagle on Shield or Dove with Tail Feathers Spread ?'
Reminds me of the 'Ruptured Duck' from 1945. This was a pin or 'medal' that returning soldiers could wear on their uniform until they could get civvies again. It came to be seen by the G.I.s still to be discharged as a very desirable item. The carving is not exactly like it but it has a similar 'feel'. Maybe the 'artist' only had a glimpse of one or only a description.
