1937 Chengteh (4 May) to Peiping via Kupeikow, f.w. Manchukuo regular issue 10f + 8f, tied by Visit Japan commemorative cds.. Transit Nanlanping (5 May), Kupeikow (5 May). Arrived Peiping (7 May). Although this cover was exchanged at Kupeikow, exchange cachet of Shanhaikwan was applied. Probably because the cachet of Kupeikow was only in use for very short time. 1937.5.4 承德經古北口寄北平,貼滿洲國普通票10分 + 8分,銷訪日紀念日戳。5.5經南濼平,同日經古北口。5.7抵北平。雖然此封經古北口交換,但仍鈐山海關賠繳戳,可見古北口賠繳戳使用時間甚短。
