Houston's newest mural honors Harriet Tubman

• The effort started in 2022 with a handful of giant murals interpreting the city's need for sustainability.

Driving the news: The mural of Tubman, entitled "From Slavery to Freedom," was unveiled Saturday on the side of Houston's storied Cotton Exchange Building at 1310 Prairie St.

• Two other murals, a replica of muralist John Biggers' "Ghana Dancers," at 1010 Lamar St., and "Greater Sisterhood," at 1302 Dallas St., also debuted.

What they're saying: "This work to honor Harriet Tubman and the countless other enslaved people who built our nation is part of our ongoing effort to connect the local commemoration of the legacy of slavery to national commemoration conversations," Harris County Commissioner Rodney Ellis said at the unveiling Saturday.

Zoom out: With the latest additions, there are now 47 murals in downtown's "Big Art, Bigger Change" open-air gallery.
