I will add to this too, Issue 2 panel 5 you will possibly show no comic book stack so try issue 2 panel 4 (any 3 hero's will do) beat the doombots in the central square, take the left exit and walk towards the screen pass 2 crates and you'll see the a item to be destroyed containing possibly your last book.
This level 2:4 is the easiest opportunity to bag the
Shake, Rattle, and Destroy for defeating 5 or more enemies. 3rd box on the right after the start you'll get the earthquake feature and stroll to the centre, await the enemies and go for it
