This variant is called #24a in the indicia but is simply a regular version of the normal issue with a new cover. Although the new cover is a flip cover, the image on the back is basically a pin-up of Tomb Raider as there is no associated story or material inside. It has been treated as a wraparound cover for indexing purposes.
This issue is a variant of
The Darkness (Image, 1996 series) #24.
