This upgraded scanned version of ACG's La Salle Publishing's January 1945 "Merry-Go-Round" [No#] adds Pages 1 and 2 of the book's first story, "Judge Beaver", which form the two sides of the missing first inside page of the book. They were copied from ACG's Ha Ha Comics #64, which reprinted the story. Also missing, and still missing, are (1) the inside front cover - which had a 1-page gag with the indicia below; (2) the inside back cover - which had a 1-page gag; and (3) the back cover - which had a poster-styled drawing of some of the book's characters. I also removed the duplicate pages of the "Laffy", "Angus McSnoot", "Hard-Hearted Hannah", "Mortimer Mutt", and "Rowdy & Dowdy" stories, as well as a few others. There are only 122 pages out of the 130 advertised on the cover. So, it seems that at least one drawn story is missing, either from the front of the inside pages before "Judge Beaver", or after the book's existing last story, "Blowaway", in addition to the missing 3 cover pages other than the front cover. The torn edges of the blank page margins have also been cropped some, to even them off.
