Here's a vintage WW2 Homefront kid's Pinback button given out by Kellogg's cereal to promote PEP.  It's of the 402nd Bomber Squardron and features their unit logo.  Measures 3/4" diameter. Just a couple tiny scuffs on the front. Decent example.  Guaranteed to please the new owner or I'll buy it back.  Check my Feedback.  Free shipping.
