Art All Day returns on Saturday, Nov. 2, with its annual afternoon of open artist studios, gallery exhibitions, live art making, mural installations, and walking, biking, and trolley tours.   The citywide celebration that attracts thousands of visitors, hundreds of artists, and scores of venues runs from noon to 6 p.m.   The event launched in 2012 is produced and coordinated by Artworks Trenton, the nonprofit arts center that houses galleries and studios and coordinates the noted Art All Night event in the spring.   Art All Day visitors simply go to Artworks, located at 19 Everett Alley where it intersects with South Stockton Street, and pick up a map/program for a self- or coordinator-guided tour.   Returning artistic or cultural venues displaying art are TerraCycle, with its walls covered with Jersey Jam-inspired graffiti; Latin American Legal Defense and Education Fund (LALDEF), showcasing artists in Trenton’s vibrant Hispanic Chambersburg neighborhood; Mill Hill Saloon’s exhibition by the Trenton Photo Club; the Blacksmith of Trenton, where a forge has operated since 1863; the New Jersey State Museum, offering fine art exhibitions and children’s projects; Trenton Community A-Team’s studio exhibition and sale; the 1719 William Trent House Museum; and more.   New venues include Shiloh Baptist Church, Freedom Skate Park, and Hanover Creative. New attractions include the refurbished public art installation of internationally known video artist Nam June Paik, new murals created by Trenton artists, and the artistic crosswalks painted at several city intersections.   The day ends with a reception at Artworks’ galleries from 6 to 8 p.m. featuring the Art All Day participating artist group show and a solo show by Trenton photographer Habiyb Shu’aib.   Events are generally free, but some events or activities may include a small fee to defray costs. Artists’ works will be for sale.   For more information or to link to a mobile site map, visit the Artworks website.
