Mixed lot of vintage military and union memorabilia ~1945

This is a small mixed lot of vintage military and union memorabilia. The standout piece is a 1945 Tacoma, Washington Building and Construction Trades Council AFL pinback button, bright yellow with Mount Rainier in the background. Alongside it is an American Junior Red Cross pin, the fold-over collar/lapel type from the mid-20th century. Military pieces include a USMC EGA collar insignia (one pin broken, the other bent), a USA sweetheart pin with attached silver oak leaf (Lieutenant Colonel rank), and three small vintage keys—likely for lockers, footlockers, or small padlocks. The matting in the photos has half-inch squares for scale, so you can get a sense of size. Everything pictured sells together as a single lot.
