Unknown RPEC-Yakima Indian Chief Lapel Pin – Retired Public Employees Council?

This pin features a design with an American Indian chief wearing a feathered headdress at the top. Below the face are the letters “RPEC YAKIMA.”

The meaning of “RPEC” is unclear, though it may relate to the Retired Public Employees Council, an organization representing retired public workers in Washington State. “Yakima” likely refers to the city or region in Washington.

The pin measures approximately 3/4 inch in width by just over 1/2 inch in height.
