Did you miss out on snagging an Obama Inauguration SmarTrip card in 2008? Well, WMATA is releasing another limited-edition card tomorrow to commemorate black history. In fact, Metro riders can choose from four different cards that celebrate the opening of the Smithsonian’s National Museum of African American History and Culture.

The first card features a photo of the museum itself, which is slated to open September 24 with an appearance from President Barack Obama and a music festival with performances by Public Enemy and The Roots, among other artists. The next two cards feature notable black figures Harriet Tubman (whose face is also slated to appear on the $20 bill) and Frederick Douglass., whose D.C. homestead is still preserved by the National Park Service. And the final card features the Parliament-Funkadelic Mothership, “an iconic stage prop in African-American musical history,” according to a release from Metro.

“Metro’s diverse workforce and ridership reflect the diversity of our region, and we’re honored to play a role in connecting the public to this important new Smithsonian museum,” said Metro General Manager Paul Wiedefeld. “These limited-edition SmarTrip cards commemorate the significance of having a museum on the National Mall that celebrates the richness of black culture and the vast contributions made by African Americans to our society.”

The cards are available online tomorrow, at some Metro sales offices beginning Monday, and at Metrorail stations starting next Friday. They cost $10, and come pre-loaded with $8 in stored fare value.

“We hope riders will purchase the SmarTrip cards not only to keep them as souvenirs but to use them to take Metro to the Museum,” said museum director Lonnie Bunch in a statement. Given Metro’s proposals to decrease service hours, though, the cards may be better served as souvenirs.
