White suffered a stroke days before passing away last month. Fans turned out to show their love and support at her star on the Hollywood Walk of Fame.
Since White was known for her animal advocacy work, Mattie added a QR code to the mural so people walking by could donate to the local animal rescue Wagmor Pets in White's honor.

"She was an advocate for animal welfare and animal rescue. I want to make sure it's accessible to people to give back to the community," said Mattie.
