Dark Horse plans three special releases in June to tie into the release of the Sin City: A Dame to Kill For film on August 22nd (see "Lady Gaga in 'Sin City 2'"), including a colossal omnibus collecting the entire Frank Miller saga in one volume; Frank Miller: The Art of Sin City in a new trade paperback edition; and a reprint of the long-out-of-print A Dame to Kill For 1993 hardcover edition. 
Frank Miller’s Big Damn Sin City includes all seven volumes of the hard-nosed crime drama in between 1344 and 1360 pages (TBD), retailing for $100. 
Frank Miller: The Art of Sin City was originally released in 2002 in hardcover.  The new $25 trade paperback edition will feature the hardcover contents in the new format.  
The 212-page hardcover reprint of A Dame to Kill For ($24.99) will include the specific story tied to the new film.   
All three books will be released in the direct market on June 25, and probably around July 8th in bookstores. 
In addition to the movie, there’s a long-gestating Sin City TV show in development that getting some recent attention (see "'Sin City' TV Show").
