Picked this one up from Pedigree Comics just now. A landmark issue in that it features the first pairing of writer Denny O' Neil with artist Neal Adams. The two would go on to greatness, of course, with the GL/GA run a few months after this. This issue also takes Batman into a more gothic area, which would continue for years throughout the seventies. Definitely one of the holy grails of my collection. And my first signature acquisition since 2016. Four more Adams books to go. Enjoy.
