Less than 24 hours after its launch, a Kickstarter campaign by Jeremy Kirby to fund a coffee table book devoted to his legendary grandfather Jack Kirby has already exceeded its $7,500 goal.

Titled The Life and Times of Jack Kirby, the hardcover will feature hundreds of personal photographs and artwork, and a never-before-seen play written by Jack Kirby called Frog Prince.

"Years ago (1997 to be exact) I wrote a screenplay and shared it with my grandmother," Jeremy writes. "She did what every grandmother would do after reading her grandson's story and told me how wonderful it was. But then she stopped for a moment as if pausing to think. She had me wait where I was and I saw her go into her closet. She reached into a box that was on a shelf and pulled out a dusty old folder. She handed it to me and said 'your grandfather would have wanted you to have this.' It was a play that he had written.  I have since showed the play to friends of the family and not one had ever heard of its existence."

The higher-priced pledge incentives offering signed Fourth World comics and original Kirby art are, not surprisingly, already gone. However, there are still other goodies to be had. The campaign ends June 20.
