Notes:
While this numbering shift from v2#4 (10) to v3#9 (11) seems abrupt and strange, some observe that v3#9 is the indicia volume and issue number that this month's issue of Cat-Man Comics should have had, while the Cat-Man Comics issue from this month is v2#6 (19). If one assigns v2#5 to the month during which Cat-Man published an issue but Captain Aero does not, then it appears that Captain Aero and Cat-Man simply switched indicia numbering.
