With Jack Kirby's birthday just 11 days away, his granddaughter Jillian has kicked off the fourth annual Kirby4Heroes campaign to help creators in need. Watch the launch video below.

In celebration of what would've been the comics legend's 98th birthday, on Aug. 28 retailers across the country will throw "birthday parties," and donate a portion of that day's proceeds to The Hero Initiative, a nonprofit organization dedicated to providing a financial assistance to creators. Many artists also participate in Wake Up and Draw, in which they create illustrations in tribute to Kirby and then auction them later on eBay, with the money going to the nonprofit.

Phil Hester, who last year drew 97 pieces of art to celebrate Kirby's 97th birthday, will be back to try to top that on Aug. 28, with 98. All will be auctioned on eBay.

When Kirby4Heroes began in 2012, it raised $5,000 for The Hero Initiative; that figure doubled in 2013, before reaching $15,000 in 2014. This year, Jillian Kirby is setting a $20,000 campaign goal.

Individuals are also encouraged to donate directly to the organization on Aug. 28, and type "Kirby4Heroes" in the special instructions field. The Kirby4Heroes website keeps a running list of retailers participating in special events on Aug. 28.
