This was originally completed to be a stand-alone lead story, ending with Rita calling off the wedding and returning to the team, then the additional pages to expand it to issue-length and have the wedding actually happen were created.
Appears between pages 7 & 8 of first chapter. Previously in December 1963 issues. A list by Lionel English also gives the penciller and inker as "Sheldon Moldoff" in most of the issues this PSA appears in. Creator credits from a list by Lionel English.
Letters are clearly by Starkman and not Field, understandable because the second chapter was not part of the story as originally planned.
Elasti-Girl marries Mento. Mento gets a new costume.
Letters from readers Patrick Stout, Joe Harris, Kathy Hiers, and Marshall Lanz with editorial replies. Also included is the collectors' segment "The Swap Shop" and a paragraph of replies to readers whose own comments are not reproduced.
