A beautifully engraved 1961 commemorative set from Yugoslavia, featuring five classic botanical designs printed by Courvoisier S.A. Each stamp presents a different medicinal plant in vivid detail: Digitalis Ambigua (10 para), Hyssopus Officinalis (20 para), Origanum Majorana (15 para), Althaea Rosea (40 para), and Crataegus Monogyna (25 para).
This set was issued for the 1941–1961 anniversary period, making it historically appealing to specialists of Yugoslav thematic philately. The artwork by M. Zlamalik is highly regarded for its accuracy and rich color palette, making this a desirable addition to any flora, medical, or engraved-stamp collection.
Collectors value this issue for its clean typography, expert printing quality, and its representation of mid-20th-century Yugoslav design excellence.
