The Hyde Collection in Glens Falls launches its largest ever exhibit of American folk art this weekend. "A Shared Legacy: Folk Art in America" opens Sunday and continues through the end of December. The exhibition includes more than 60 works from the 19th and early 20th century, from the collection of Barbara Gordon.Folk art is rooted in personal and cultural identity, and made by artists who were either self-taught or had very little training. Created for ordinary people rather than just the rich, folk art was the prevalent art form in the U.S. for more than a century. The exhibited works include a range of paintings, woodcarvings, trade signs, furniture, and carousel animals.Jonathan Canning, the Hyde Collection's director of curatorial affairs, says the works in the exhibition reflect American creative expression during a period of great political, social, and cultural change.
