Additional works by Josephine Nivison Hopper have continued to surface, as reported by Elizabeth Thompson Colleary. Jo's watercolors were exhibited at the Edward Hopper House Art Center, Nyack, NY, in 2014 and a few examples were included in an exhibition of "Edward Hopper as Illustrator" at the Norman Rockwell Museum in Stockbridge, MA, also in 2014. In 2016, the Provincetown Art Association and Museum, Provincetown, MA, announced that 69 drawings and watercolors by Jo Hopper were included in the gift of Laurence C. and J. Anton Schiffenhaus, along with 96 drawings by Edward Hopper. An exhibition of these works, "Edward and Josephine Hopper from the Permanent Collection: drawings, diaries, letters, watercolors," opened in August 2017. The exhibition was extended "due to the overwhelming interest by scholars, critics and visitors" and remained on display until August 2018.
