German occupation of Serbia stamp year 1941 20d Airmail MLH

1941, during the German occupation of Serbia the occupying authorities issued a set of airmail stamps made by overprinting existing Yugoslav airmail stamps with a red diagonal “SERBIEN” overprint. These are catalogued (Scott) as Scott 2NC1–2NC10 (often shown as 2NC1–10) and are a common specialty collecting area.

What they look like (quick ID):

• The base designs are the pre-war Yugoslav airmail airplane/airmail vignette designs (various denominations).
• A red diagonal overprint reading SERBIEN was applied (sometimes different fonts/shades). Many examples show the plane vignette visible behind the overprint.

When and how they were issued / catalog notes:

• These overprints date from 1941 (the early occupation issues) and form the first airmail-issue group for occupied Serbia; they appear in standard catalogs and auction listings under the German-occupation Serbia issues. Expect Scott numbers 2NC1–2NC10 and corresponding Michel listings. Variants (double overprints, color shifts, mint/used, hinged/NH) appear and affect value.
