Notes:
The correct name might be "Hit Publications, Inc." as no indicia have been spotted.
Worth Carnahan's daughter Cynthia Woody spoke of Worth Publishing Co., Bilbara Publishing Co., and Hit Publishing Co. as her father's companies in an interview in Comic Book Marketplace #71, titled "The Unknown Publisher: Worth Carnahan"). Bilbara and Worth have been confirmed, so it seems likely that she is remembering all three correctly.
Both Howard Keltner and Jerry Bails list this company as Hit Publications, Inc. However, this sort of very minor publishing company name detail has often been misreported. CGC has labeled some slabbed issues Hit Publications, but others United Features Syndicate (confusing this O.K. Comics with UFS's Okay Comics), so that does not appear to be a reliable source of confirmation.
