international letter + domestic airmail rate, tied by Kangting
bilingual cds. Transit Chengtu (4 Apr), Shanghai (6 Apr). On front
with “AIRMAIL SERVICE IN CHINA ONLY” cachet. Scarce example of
Batang, dated just after the confrontation between KMT and CPC
during Long March. The usage of Kangting instead of Tatsienlu cds
is also rather early.

康定三格點線日戳。4.4經成都，4.6經上海。正鈐“AIRMAIL SERVICE IN CHINA
