A beautiful three-stamp wildlife set from Yugoslavia, featuring finely engraved illustrations of native forest animals printed by Courvoisier S.A. The set includes the European Hare (Lepus europaeus), the Pine Marten (Martes martes), and the Red Squirrel (Sciurus vulgaris)—each shown in dynamic motion within natural woodland scenery. Designed by M. Zlamalik, these issues are prized for their rich naturalistic detail, sharp linework, and classic mid-20th-century Yugoslav aesthetic. A desirable thematic group for collectors of wildlife, fauna, and European nature issues.
