The least odd thing about this Dexter Press DT-86863-B (and W-58) card is that it is unused and has serrated edges. Then we move on to four different dates imprinted (1961, 1962, 1964, 1965) and the notice that this is an OFFICIAL World’s Fair Post Card showing the “economics of a typical small town at work” and advising that “Those who become engrossed can register for a full-credit graduate course in economics taught on the grounds by Adelphi College.” Gee, you just thought you were going to the Fair.   Grade: 3
