WB Gives Their Water Tower A DC TV Makeover
Supergirl Melissa Benoist was in attendance at the event along with EP Marc Guggenheim.
"Such a crazy feeling," Benoist posted on her Instagram. "I mean really. Kara on the water tower at @warnerbrostv w/Flash, Arrow and Gotham @dccomics."
The banners will be on display for the next 90 days.
