Description: This 1.20-koruna definitive postage stamp was released by the Czechoslovak Socialist Republic (ČSSR) as part of a multi-value definitive series highlighting various civil professions and specialized fields of labor. The highly detailed vertical artwork captures a scientist clad in a laboratory coat, deeply absorbed in documenting research observations inside a notebook while his hand rests on the focus adjustment knob of a compound microscope. The country name "ČESKOSLOVENSKO" spans the entire top margin, underscored by the prominent denomination "1,20" in the top left corner, with fine artist signatures etched into the bottom-most border frame.
Circa: 1950s-1960s
Condition: Used - Hinged
Notes:
This piece belongs to the influential mid-century "Professions" definitive series, a set highly regarded by philatelists for its artistic promotion of specialized fields like engineering, medicine, and scientific research under state-driven economic programs. The stamp showcases the exceptionally crisp, high-contrast linear style of Jindra Schmidt, Czechoslovakia's legendary master bank note and postal engraver, whose clean cross-hatching technique perfectly captures the clinical atmosphere of the laboratory setting.
