This UX48 postal card has a "POSTAGE DUE" and a 20c meter printed from Wheeling, W. Va on it. Why is the postage due 20c instead of 4c?
The postal card was returned to Wheeling with auxiliary markings including the "RETURNED FROM EAST LIVERPOOL, OHIO DUE _ _ _ _ _ CENTS".
Perhaps was one of five returned and paid together, this one being the top of the stack?
