Special Sized 12th issue was with Neal Adams.

Neal Adams contributed so much to comics, especially to Batman. So back in April 29th, 2022, I was sad to hear that Neal had passed away. But he left such a long lasting impact and legacy throughout comics – that no one is ever going to forget him. So he will always be immortal. And he would go on to be the first really big artist/writer who has been published in major comics (in his case, Marvel and DC).
