The Palace Theater, home of Harry Potter and the Cursed Child, has replaced a poster at the front of the theater with a rainbow flag in support of the Orlando shooting’s victims.

On Saturday night, an LGBT club in Orlando, Florida was attacked by a gunman who killed 49 people. The attack is the biggest mass shooting in American history.

Given the enormity of the tragic attack, people around the world, including J.K. Rowling, have been showing their support for victims. In addition to paying tribute to a fallen Wizarding World of Harry Potter employee this morning, the author has revealed that a rainbow flag is now at the front of The Cursed Child’s Palace Theater.

The flag appears to have replaced a poster previously promoting the play, which is currently in previews. It’s a nice reminder that fans of all sexual orientations are welcomed at The Cursed Child:

Another photo from a different angle shows just how bright the flag is, even during the daytime. It looks like they’re keeping the light turned on behind the poster at all hours of the day to make sure it’s noticeable:

Way to go, Cursed Child team.
