To my Gumba 'Steve M', this post is for you
I finally got around to posting something to this fascinating section of the forum. Thank you for all your hard work in advocating WWI U.S. Aviation history.
Here is a set of what is commonly referred to as 'Sweetheart' wings which would have been worn by relatives back in the States to commemorate their loved ones service in that branch of the military. This is not to say an American Aviator did not purchase this set while serving overseas to wear on his OS cap.
It is a finely crafted jeweler piece stamped STERLING on the reverse & with a heavy duty drop-in clasp. These 'wings' measure 1.75" (4.5cm) across.
