A new mail-voting exhibition is a reminder that its use dates back to the Civil War

Four years ago, millions more voters in the U.S. became familiar with voting by mail.

But a new exhibition at the Smithsonian’s National Postal Museum opens Saturday as a reminder that earlier generations of voters used the postal service to cast absentee ballots decades before the COVID-19 pandemic upended the 2020 election.

“It was sort of presented during the pandemic as a new concept for a lot of folks who may have never encountered it before,” says Carrie Villar, director of curatorial affairs at the Washington, D.C., museum that is open free to the public. “We thought with this presidential election coming up in 2024, there could be no better place than the National Postal Museum to have an exhibit where we talk about voting by mail and how it’s not a new thing. It’s been around for over 160 years in various forms.”
