1980年2月24日上海寄無錫欠資封，單貼文革紅燈記試機票，銷上海日戳。因此票無郵資效用，故作欠資處理，旁蓋上海橢圓形欠資戳。背面蓋有無錫到達戳。紅燈記試機票實寄封十分罕見，票左下角有折損。上中品。 f.w. Cultural Revolution Trial Print issue, tied by Shanghai cds. The stamp is invalid for postage, there is an oval postage due mark alongside. Wuxi arrival cds. on reverse. Extremely rare. Stamp with fault at lower left. F-VF.
