If you ever find yourself strolling down Armitage Avenue in Logan Square, you may encounter a friendly beaver on a three-foot wide baby blue button, greeting you with a simple “Hello!” The button marks the entrance to the Busy Beaver Button Company and Museum, a spot in Logan Square that has archived 60,000 pin-back buttons. They’ve got everything from a “pre-button” celebrating George Washington’s inauguration to a heart-shaped button of John Lennon and Yoko Ono. Reset sent two team members to the museum to find out what's so special about buttons. For a full archive of Reset interviews, head over to wbez.org/reset.
