On Wednesday, the late actor’s only daughter unveiled a touching tattoo she had inked on her right hand to memorialize the Oscar-winning actor, who committed suicide Aug. 11 at age 63.
“For poppo,” she captioned a black-and-white Instagram shot featuring a hummingbird in flight, with her father’s birthdate – 7/21/51 – inked below it.
“I’ll always put my hand out to shake with a smile,” she also wrote in the caption, after thanking Dr. Woo of Hollywood’s Shamrock Social Club tattoo parlor “for so beautifully bringing my reminders to life.”
Zelda, 25, has spoken out sporadically since her father’s death, including on World Mental Health Day, Oct. 10, when she urged people suffering from depression to seek help.
Zelda also spoke movingly about her father on her Tumblr page just a day after his death.
“Dad was, is and always will be one of the kindest, most generous, gentlest souls I’ve ever known,” she wrote. “And while there are few things I know for certain right now, one of them is that not just my world, but the entire world is forever a little darker, less colorful and less full of laughter in his absence. We’ll just have to work twice as hard to fill it back up again.”
