My apologies. Work has kep[t me too busy to check this stuff out more often.
The thing about the missing Four Colors is that they tend to be missing a number in the indicia at all what so ever. If you looked at the indicia of t had Space Man issue, it would probably say Spaceman # 2 or something like that. Almost all the "missing issues" are shown only as the 8 series number that has specific meaning top date title and price. An interesting example, however is Beany and Cecil. While it is almost without a doubt a missing issue, it has no such numbers in the title in the indicia. When there is no other number and the actual name of the title is in the indicia, it is usually assumed to be #1. When the 89 digit number is used in the indicia, it is almost certain, however , to be missing.
So in summary:
Indicia has title and no number: Presumed to be #1
Indicia has title and lists any issue number: Not missing for sure.
Indicia has 9 digit code where issue number belongs and is dated 1962: Probably missing
There is some debate as to whether some in the first category, such as Beany and Cecil, might actually be missing.
