“Pittsburgh Skyline, 1929” is part of the Heinz History Center's exhibit “#Pixburgh: A Photographic Experience.”

PITTSBURGH — Visitors to the Sen. John Heinz History Center can get an in-depth look at the museum’s collection of photographs as part of the new exhibition, “#Pixburgh: A Photographic Experience,” running through Aug. 20.

The exhibit highlights photography from the early 1850s through today, culled from the center’s vault of nearly one million photographs. Many of the nearly 400 featured photographs have never been displayed to the public before.

The images reflect a wide variety of subjects and time periods, from turn-of-the-century mugshots to the 1960 World Series, from the 1936 St. Patrick’s Day Flood to the Westinghouse Skybus, and from early “selfies” to Polaroids.

The exhibit also includes artifacts on loan from the Smithsonian.

Hours are 10 a.m. to 5 p.m. daily. Admission is $16 for adults, $14 for senior citizens, and $6.50 for children 6 to 17.
