1.25". Reverse backpaper from "National Badge And Novelty Co" of Cleveland which has a .5" tear but all the text remains. Button's reverse also holds most unusual silver luster spring pin with the interior wire partially beneath the collet forming a letter "S" rather than the standard semicircle. Front of the button has slogan "Protection And Prosperity." This is accented by slight coloration on their faces, a rwb shield design, and a bright gold background surrounding everything. There are a couple of tiny dots where the gold luster is not as bright as surrounding luster but this is not stain. Button has exceptionally high gloss.
