Three new exhibitions — including a recent acquisition by painter Amy Feldman — are on display at the Sheldon Museum of Art this summer.

Featuring paintings by 14 artists, “nonObjectives” is a vibrant chronicle of the evolution of reducing art to its essential qualities. The exhibition draws from the museum’s permanent collection, including examples of abstraction and color field painting. The works span decades and feature several rarely seen canvases and recent acquisitions, including “Body Buddy” by Feldman.

Other artists in “nonObjectives” include Dan Christensen, Gene Davis, Richard Diebenkorn, Lorser Feitelson, Peter Halley, Willy Heeks, Carmen Herrera, Odili Donald Odita, Sean Scully, David Simpson, Cary Smith, Leon Polk Smith and Frank Stella.

Paintings by Marsden Hartley are among the featured artworks in "Selections from the Bertha Schaefer Collection," a new exhibition at Sheldon. Shown here is Hartley's 1933 painting "Garmisch — Partenkirchen (Alpspitze)."

The other two exhibitions are “Selections from the Bertha Schaefer Collection” and “Wright Morris: Nebraska Pictures.”

“Selections from the Bertha Schaefer Collection” explores the legacy of a sizable gift of paintings, prints, sculpture and ceramics from the estate of Bertha Schaefer, a New York gallerist and interior designer. Schaefer’s bequest enhanced Sheldon’s collection in several key areas, most significantly through a gift of paintings by major American modernists Alfred Maurer and Marsden Hartley.

“Wright Morris: Nebraska Pictures” is presented in conjunction with Nebraska’s sesquicentennial celebration. The Cornhusker State figures prominently in the work of Morris, an award-winning novelist, photographer and essayist born in Central City in 1910. The exhibition features photos from the Sheldon collection that exemplify Morris’ sensitivity in capturing details of rural Nebraska in the 1940s.

"Wright Morris: Nebraska Pictures" features images shot by Morris in rural Nebraska in the 1940s. Pictured here is "Dresser Drawer (from Ed's Place, near Norfolk, Nebraska)."

Sheldon will also celebrate Nebraska’s 150th birthday during a Family Day event, 1 to 4 p.m. July 16. The celebration, which is free and open to the public, will include games inspired by the Sheldon’s collection, a party favor designing station, live music and birthday cake.

All three exhibitions are open through July 23. The museum will be closed from July 24 to Aug. 10 for the installation of energy-efficient LED lighting. New exhibitions will also be installed during the closure.
