Seattle Gum Wall Welcome to Seattle's gum wall. Some call it art. we call it disgusting. In some spots on the wall there is so much gum sticking to it that you can't see the brick beneath it. There are gum sculptures of faces, dogs, hearts, and peace signs, among others. Seattle itself is a great city to visit with many enjoyable attractions. Unless you are seriously considering adding to it, you would skip the gum wall.
