Lot# 9057

denomination 2 fen, undated, each struck with a double-ring bilingual “CANTON / 廣州” trial cancel. Printed as a vertical tête-bêche pair, perforated at the lower margin only, on plain experimental paper without “Chinese Post” background (approx. 87 × 77 mm). This represents an early testing proof from the initial stage of the postage meter system, of extreme rarity, with only one example recorded. Accompanied by a 2017 Experts & Consultants Limited certificate. Preserved in generally fine condition with period traces of handling, an important artifact for the study of the inception of China’s postage meter system and its trial use in Canton, of significant postal history and exhibition value.
