The wall in the neighborhood of Post Alley, near the Park Place Market, is known today for Gum Wall in Seattle and began receiving assistance from the tourists and locals in the early 1990s.
At the time, many people passed through the region and formed long lines to buy tickets for the local theater. Angry, they clung to their gum on the wall and, sometimes, also glued a coin.
Over the years the coins were losing ground to the gums and in 1999, the city officially the site as a tourist attraction.
