In the May 1993 Word Ways, Darryl Francis presented a presidential rectangle: the names of 37 U.S. presidents joined within a 17x29 frame. In August, Lee Sallows presented the same names within a 19x22 frame, but his names are not all joined - a fatal flaw. Fallows states that some "purist" might criticize his result, and challenges readers to "produce a fully-connected layout of the same area". It can be done easily!
