The book consists of reprints of the outermost wraps of More Fun Comics #v2#3 [15] and #v2#4 (16) (with the latter nested inside the former), followed by the outermost wraps of New Comics #v1#11.
This is *not* a rebinding, as some ads have been changed, the "It's a Dern Lie" feature on the final page of New Comics #v1#11 has been moved and replaced by an ad, and a feature from New Fun #v2#3 [15] appears in the middle of the #v2#4 (16) section.
The inside front and back covers of this issue are completely blank, and the cover is made of a stiffer tagboard than the usual cover stock.
Also, at the border between those two issues is a wrap with outer pages from #v2#3 [15] and inner pages from #v2#4 (16), clear proof that the originally printed signatures were not just rebound. Oddly, the inner break in the New Comics #v1#11 quire does not line up with the feature boundary, splicing a page off of each of the adjacent features.
