currently running Kickstarter for the next new Steve Ditko comic, #9 TEEN, which as you'd expect is the nineteenth release in the series of 32-page comics they've released since 2008. Covers and titles of the previous issues of the series and other Snyder/Ditko publications over here.
This new one looks to feature The Madman, who has previously appeared in 8-page stories in:
DITKO PRESENTS 
A DITKO ACT TWO 
DITKO NO. 5 - FIVE ACT 
ACT 8, MAKING LUCKY 13, THIRTEEN DITKO'S 32S 
NO. 16 - SIXTEEN 
Plus a few other recurring features from the last few years.
