1.25". This is an original button paper which Ted Hake acquired decades ago and which has recently made into a button with text on the curl reading "Original Paper Pinned By tedhake.com." Beneath clasped hands and the slogan "United We Stand, Divided We Fall" is a portrait of "Mrs. Francis K. Bolling, Founder." Tiny bit of gray tone upper left on the letters "IN" with everything else displaying Mint. We've not been able to find any history on this group or this woman but given the majority of the original papers it came with we estimate from the late 1920s. One of only one example found.
