John Jackson Miller had an interesting column the other day for Comic Book Buyer's Guide where he pointed out what is most likely an amazing fact.

Detective Comics #853, the second part of Neil Gaiman's "Whatever Happened to the Caped Crusader?" storyline, was the number one selling comic for the month of April 2009.

That is almost certainly the first time in the history of its SEVENTY-THREE year existence that Detective Comics could make that claim.
