Early Oklahoma IOOF pin with all seeing eye and a map. Circa 1920 +/- 5

What a fascinating pin. The all seeing eye and a map on a pin, wow. Judging from the style, subject matter, and other pieces in the collection this piece should date from the teens. It has some issues with minor rust spots on the face and a small rust spot on the back. Please see the pictures to determine the condition of the item for yourself. Always happy to answer questions. And happy to receive offers. Cheers!
