2:1 The next 3 pages take us on a whirlwind tour of Gotham City, the home of the Batman. From Evanston to Sommerset, Gotham has probably never been described in such geographic detail in the 47 years since Batman premiered.

Veitch's graffiti story "The Everlasting Tag", EPIC #28

3:1 Captain Jon Logerquist was a Swedish mercenary who founded Fort Adolphus, which became Gotham City. Gotham's history is further shown in issue #86 ,1989.
Note the barrel of "toxic waste" above the credits.
Also note the graffitti that says "Herpes". Contributor Jonathan Schaper points out that "This is an in-joke referring to a Rick Veitch short story from EPIC ILLUSTRATED #28 (1985). The story takes place in a future in which all crime, poverty, etc. has been eliminated EXCEPT that someone manages to spraypaint the tag 'Herpes 2000' on everything while evading detection." The story is reprinted in Veitch's "Shiny Beasts" paperback (2007, King Hell).

The killer/lawyer is Harvey Dent, alias Two-Face.
