Batman mini-series comic books DC Comics #575-578. NM

Four near mint condition direct edition (came in the mail) Detective Comics Books. #575-578. It’s a Batman mini series, kind of interesting. Parts 2, 3, & 4 are illustrated by Todd McFarlane but part 1 is not, and these are the only DC Comics I’ve ever seen with McFarlane illustrating. He’s usually with Marvel. Printed from part 1 in June 1987 through part 4 in September of ‘87.
