Elliot S! Maggin recently announced that he will be publishing a brand-new 2017 edition of
Superman: Miracle Monday!
I have put together a small page about this new edition right here: https://www.supermanthroughtheages.com/theages/MiracleMonday/
Elliot has corrected typos and done some editing; he will be the reader for the audio edition; and there will also be both a paperback and an e-book version.
The cover artwork shown above is by Ken Penders - the source is the Superman Homepage.
The artwork shown on
Elliot's page is presumably the version for the finished book:
One more thing - the announced publication date is May 15, 2017 - Miracle Monday 2017.
