Easter Egg Basket #2 - Classics Illustrated

Check out the comic book shelf in the background of a scene from The Dark Knights Returns Part 1:

Top shelf (from left to right) appears to be:

• Swamp Thing Volume 8 Trade Paperback "Spontaneous Generation"
• Sandman #1
• V For Vendetta Trade Paperback

Bottom shelf (again, from left to right):

• Crisis on Infinite Earths #1
• Watchmen #1

All are from DC Comics or DC/Vertigo, considered innovative and were popular around the same time (more or less) as when the Dark Knight Returns comic came out.
