We talk about this on Podcast 97 (link to the list follows)...The Top 75 Batman Covers of All Time.
This one by Legendary Artists Neal Adams coming in at 61 is one of Patrick Riley's favorites. He shares the story of how he discovered Kimmy had an original issue as a kid and it had survived the travels in time (sort of).
Iconic cover by Carmine Infantino is 58th on the list...Riley and Kimmy agree this one should be in the top 5.
Neal Adam's Batman 241 is 27th on the list. Patrick Riley would have it in the top 5.
Jim Lee's famous cover comes in at 34th on the list. Patrick Riley would have it in the top 5.
