In Philip Barter: Forever Maine, award-winning author Carl Little traces the painter's life from a formative trip to California in the 1960s; to downeast Maine where Barter and his wife, Priscilla, made a life immersed in art for themselves and their seven children; to critical acclaim for Barter in the 1990s and his most recent paintings from 2016 and 2017.

By the early 1990s Barter had come into his own. In a review of a Barter retrospective at the Bates College Museum of Art in 1992, Maine Times critic Edgar Allen Beem noted the painter's progress "toward a more idealized vision of the northern landscape, a vision tempered by the spiritual simplicity of Arthur Dove and the physical simplicity of Milton Avery." The Farnsworth Museum and Portland Museum of Art also acquired Barter's work. He was the subject of a feature profile in Down East magazine and went national when, in January 1995, Tim Sample highlighted his life in art in one of his "Postcards from Maine" segments on the CBS Sunday Morning program hosted by Charles Kuralt.
