Zelda Williams, the daughter of Robin Williams, has etched a tribute to her late father onto her hand. Williams’ tattoo, seen on Instagram, is of a small hummingbird floating on the side of her hand. Her father’s birth date, “7.21.51,” is beneath the bird, on her wrist. “For poppo,” Williams wrote. “I’ll always put my hand out to shake with a smile.” The Instagram post is Williams’ first since she quit the image-sharing site two months ago, after her father took his own life.
