1963: The Lost Annual
In 1993, Alan Moore worked on a miniseries for Image Comics called "1963", which is a homage to the Silver Age of Marvel Comics. After six issues published, there was suppose to be a giant-size 80 page annual BUT it never happened because creative differences and other matters within Image Comics.
Between 1963 and the Image United event, I think I can piece together what might have been for the so-called "Lost Annual" with some adjustments within the Image Comics Universe (such as incorporating Maximum Press/Awesome Comics)... and more.
