1961 Czechoslovakia Butterfly Postage Stamp Series

A partial set of five vintage postage stamps from the Republic of Czechoslovakia, originally issued in 1961 as part of a classic 'Butterflies' (Motýli) series. Each stamp features highly detailed lithographic illustrations of different lepidoptera species set against a backdrop of clouds and flora. Specifically, the set includes the 15h (Anthocharis cardamines), 20h (Zerynthia polyxena), 30h (Parnassius apollo), 40h (Papilio machaon), and 60h (Aglais io) denominations. The artwork is credited to Max Švabinský and engraved by Jindra Schmidt, reflecting the high-quality craftsmanship of 20th-century Czechoslovakian philately. The stamps are printed on paper with distinctive perforated edges. At least three of the stamps show visible circular postmark cancellations (c.d.s.) in black ink, indicating they are in 'used' condition. The colors remain relatively vibrant with soft pastels and fine line work, though there is some light toning consistent with age. They are currently housed in a transparent philatelic mounting strip. The presence of the country name 'ČESKOSLOVENSKO' and specific denomination suffixes 'h' (haléř) denote their origin from the Socialist Republic era.
