This 1940s Chinese letter cover, connected to tax payments during the late Republican era, features a remarkable ensemble of regional revenue stamps from the Shantung Factory, affixed circa 1946. Among the items is a Type II imperforate $300 Slate stamp, listed in Padget as LA 174A and in Paau as NWP7, notable for its clean design and economic context amid post-war restructuring. It is accompanied by a Type II $100 Rosy-Brown on Pale Violet issue with clean perforations (Padget LA 174a), and a rare imperforate vertically tête-bêche pair of the $10 Red (Padget LA 172Aa), which is of particular philatelic interest due to its unconventional layout and limited documentation. Catalog inconsistencies further enhance the significance of this ensemble: Padget describes Type I only as perforated, while Paau asserts they are imperforate; Type II issues are treated as both perforated and imperforate in Padget (excluding the $10), whereas Paau lists all but the $30 denomination as imperforate. These disparities highlight the complexity and transitional nature of Chinese local revenue production in the 1940s, revealing the challenges of cataloging under turbulent historical and administrative conditions. The cover itself presents an authentic postal-fiscal intersection, offering a rare glimpse into provincial taxation infrastructure, rural iconography (with farmer motifs), and the practical use of revenue issues in wartime China. Condition Very fine cover with cleanly affixed revenues, minor natural aging, and clear fiscal markings. Estimate "$100 – 140".
