The first three issues are regular-sized issues and the rest are digest-sized issues, #7 being a 'tall' edition.
This has been a difficult series to get a handle on but I think I've finally sorted it out.
The problem begins with the confusion evident in the Yaffa office as to whether this is a series titled Jungle Action, Black Panther or both, as you can see by the alternating cover titles and indicia titles. For example, the indicia title on #5 is Black Panther, but is Jungle Action on the unnumbered recycled reprint. The confusion stems from the fact that the Yaffa series is initially based on material originally appearing in Marvel Comics'
Jungle Action but quickly switches gears into reprinting material from the dedicated Marvel
Black Panther series, and proceeds to flip flop between the two.
The other problem is the sixth issue was misnumbered as Jungle Action #2. This issue is a digest-sized reprint of Jungle Action #1. The duplicated issue number did not make sense. This coincided with the 'missing' Black Panther #4 - no such issue had appeared in collector's circles - so it seemed to me that the misnumbered #2 was intended as #4 in the series. However, now that a copy of Black Panther #4 has turned up, the misnumbered #2 takes its rightful place in the gallery slotted in between #'s 5 and 6 based on the publication date.
Given #1 and #5 were recycled within the series and #2 was recycled and retitled
Jungle Beast, I suspect #3 and #4 may have been reissued as either unnumbered or retitled editions. TBA.
