The International Walldog and Sign Art Museum has been open since 2010, but it definitely has quite a collection of history. Located in Pontiac, you will find this brick building full of old signs and advertisements throughout the year. They do not just have advertisements, as you will also find classic old murals, or replicas of them, inside the building as well. There whole purpose is to preserve art from throughout the years, and they have definitely done just that. They do have another separate room just for art and various art pieces, but their main focus is on old murals and artworks from throughout the ages.
