I can only find the Shazam Justice League issue 0 of the New 52 Shazam on the service. Didn’t he do a whole book?
The New 52 Shazam! trade is a collection of the Shazam! back-up stories from the New 52 Justice League series.
These are the issues of Justice League (2011) that you can find Johns’ Shazam in: 7-11, 0, 14-16 and 18-21.
Thank you, @Vroom!
@chrishogue You’re welcome.
In case you weren’t aware, Shazam also remains a fixture in Johns’ Justice League after his introduction.
