We all have trade paperback (TPB) collections we'd like to see. Here's one of mine:

Timequake is the only unified set of What If? stories that I know of, and I think that fact alone makes it worthy of reprinting. Pretty simply, a group called The Time-Twisters cause some multiversal havoc, trying to be the last people in time. A team of Marvel heroes from various realities has to band together to stop them. The issues relate back to two previous issues of both What If? series, and to two events: Operation: Galactic Storm and Atlantis Attacks. The final issue is where the heroes band together to stop the Time-Twisters.

I included #1 of the 1977 series, and #24 of the 1989 series, because they relate directly to two of the Timequake issues. However, I think I'd put them at the end of the TPB, as "easter egg" extras, rather than at the beginning, in order of publication. I think putting them in the front of the book would break the flow of the Timequake story, and may confuse unfamiliar readers when they don't seem like part of the arc. If this story arc ever does see print, Marvel will more than likely leave those two issues out, but hey, this is my dream, so I'm including them.

For the cover, I'd go with What If (1989) #39, because it shows the Watcher in the background, and doesn't look like it's linked to any one particular scenario.

Thanks again!
