#4: The Market Theater Gum Wall

While art is inherently subjective, the Gum Wall at Seattle’s Market Theater, grown from a tradition of sticking gum-pennied walls, metamorphoses from quirky art to repulsion with a moment’s thought, highlighting the subjective boundaries of communal artworks.

The visual of millions of chewed gum pieces festooning walls along pathways hardly conjures up cleanliness. This Gum Wall ranks among North America’s top five germ-infested attractions, challenging the notion of what we consider ‘tourist-friendly.’
