Since its founding in 2002, the Winters Participation Gallery (WPG), an arts nonprofit, has focused its support on emerging artists in the Winters area. What began as a brick-and-mortar organization, evolved into a "gallery without walls" when the Board decided to concentrate on murals created by students. Over the last six years, several high school Senior Capstone murals have been sponsored by WPG, and six full-size murals have been created through the auspices of WPG's summer class titled "The Winters Historical Mural Project" in which students design and paint a mural under the direction of professional muralists.

During 2022, Winters Participation Gallery and twelve students painted the north wall of the Winters Post Office at the corner of Railroad and Baker Streets. Plans are already underway for the 2023 mural, with longer-range plans to partner with the Historical Society of Winters in creating a walking tour of town featuring historical landmarks and the murals.
