Q: How do the team logos, hash marks, etc., get changed so fast at the new Mercedes-Benz Stadium?

—John Vaughn, Newnan

A: The turf is scrubbed and repainted by crews that work overnight, a stadium spokeswoman told Q&A on the News.

The process will happen again this Saturday night into Sunday as Mercedes-Benz Stadium is hosting an MLS Atlanta United match on Saturday and then the Atlanta Falcons’ NFL home opener on Sunday.

Q: Who did the sculpture of Dr. Martin Luther King Jr. at the Georgia Capitol?

—Ede Martin, Atlanta

A: The sculptor was Martin Dawe. He was inspired by a photo of King walking with adviser Bayard Rustin during the Montgomery Bus Boycott and then viewed a video interview from the March on Washington to get the best likeness of King's features, he previously told the AJC.

The sculptor described his depiction of King as hopeful, yet stern. His stance “looks like he’s stepping off,” Dawe told the AJC. “It suggests a beginning and a hopefulness.”

Over the last 30 years, Dawe’s Cherrylion Studios in Atlanta has produced more than 30 large-scale public art installations, which are among hundreds of commissions, according to its website.
