For the second year in a row, Jack Kirby's youngest granddaughter Jillian is commemorating the legendary artist's birthday by spearheading the Kirby4Heroes campaign to help creators in need.

On Aug. 28, what would have been Kirby's 96th birthday, fans are asked to donate to The Hero Initiative, the only industry organization that provides financial assistance to creators who have fallen on hard times.

Some retailers have also pledged to donate a percentage of their profits on that day. Writing on Hero Complex, 17-year-old Jillian Kirby says some stores will host "birthday parties" for her grandfather and auction off original art to benefit The Hero Initiative. This year's goal is $10,000, nearly double what was raised in 2012.

"I started the Kirby4Heroes campaign as a way to connect with my grandfather, who died the year before I was born," Jillian writes. "I’ve grown so much closer to him through my endeavors in this area. I have to admit I’m astounded by him as an artist, family member and just a kind human being. Raising funds for those in the comic book industry in need of financial and medical assistance is a cause my grandfather Jack would have championed. He never turned his back on a person in need."
