So these were sketched up in 1976? Would have been cool to see another Cracker Jack parody, since Cracked Jerk was only released in the die-cuts set.
But I totally can understand the rejection by Topps due to potential C&D complaints.
Looking back to the die-cut, it looks like there was supposed to be copy underneath the "Cracked Jerk" title that was whited out for some reason.
