This issue is a variant of Legends of the Dark Knight (DC, 1989 series) #1 [direct]. There exist further variants.
This issue alone had a double cover (8 pages). The outer front cover came in four colors. The data on this line refers to the inner front cover, which is more in line with subsequent front covers. Dean Motter did the cover design and logo for this first arc.
The writer explains the logic behind the double cover and importance of the debut of a new Batman solo book, the first since 1940. This appears on the inside front (outer) cover.
The Batman Year One story is expanded a bit in this storyline.
This is a poster for the movie Shocker from Wes Craven.
