Here's a photo of Neal Adams with Superman creators Joe Shuster and Jerry Siegel, circa 1975, in the period right before
the first Superman movie, when he was struggling to get them compensation from DC/Warner.

Some interesting behind the scenes text of how thoroughly Shuster and Siegel were screwed over the rights to Superman.


Here's another photo showing Adams with Shuster, Siegel and Jerry Robinson. Apparently they first met and got to know
each other at ACBA meetings.
