After it was announced, Frank Miller’s upcoming spread for the special anniversary issue of Detective Comics #27 has been one of the most anticipated parts of the issue. But a later announced cover for the issue appears to have been cancelled.
DC recommended that retailers increase their order of Greg Capullo’s cover instead to allow for orders to remain the same.
Despite this development, it remains unknown if Miller’s spread for the issue will still remain as part of it.
