Sizes are 13/16” to 1”. First two buttons “Elect Hoover President” and “I’m For Hoover” are both unlisted in Hake. The “We Need Hoover Now” button is Hake #138. This has tiny dark age dot on very top edge and a couple of other much fainter and barely seen marks near the bottom. Still full bright color and gloss. Last is a highly domed brass button. This is Hake #2044. There are two very shallow dents above and below the last two letters of his name but they really just catch reflected light and do not detract visually.
