Croatian Model Aeroplanes Semi-Postal Set

Croatia · 1942 · 2.50+2.50 Kuna, 4+4 Kuna, 2+2 Kuna, 3+3 Kuna

This set of four semi-postal stamps from the Independent State of Croatia features various aircraft designs, including a glider over mountains, a seaplane over a coastal town, a monoplane over a landscape, and a figure launching a model airplane. Each stamp carries a surcharge for 'Za Hrvatska Krila' (For Croatian Wings).

Issued during World War II by the Independent State of Croatia, a puppet state of Nazi Germany and Fascist Italy, these semi-postal stamps were intended to raise funds for the 'Croatian Wings' aviation program, likely supporting the air force or youth aviation initiatives.
