Badgeguy - to answer your original question - the emblem did not change even though the members of the organization shifted from college age women to community women. It's always been a gold star with the letters P.E.O. on it. In the last decade, members have been given the option of having the standard pin back emblem or a tie-tack back. The emblems also have the name engraved on the back. It may have been a little bigger at one point, prior to 1900. The only members whose emblems are a little different are those who serve as State/Provincial/District Presidents and those who serve on the International Board. The International Board members have bigger emblems with a diamond on the top point. (see the cover of the P.E.O. Record
