Artist division of labor based on credits to issue #1 -- this issue simply credits all three of them as "Cover Artists". Unusually, the cover is *not* signed.
The script in the back of this issue makes it clear that the older flashbacks were supposed to be portrayed by mixing distressed artwork from those time periods into the current art, but this was not done.
There is a large numeral "4" above Logan and Hisako in the panel occupying the lower half of the first page. In the absence of any other explanation, I am assuming it is the title of the story.
Scripts for the two stories in this issue, with art excerpts from the first story (referred to as "part three") and uncolored art excerpts from the second (referred to as "part two"). Note that the stories in the previous issue were referred to as parts one and two, so it's not clear whether this "part two" should have been "part four" or whether there is some other error.
