Issued by the Schweizerische Nationalbank on 22 December 1960, this note belongs to the sixth series of Swiss banknotes (Series 23), which circulated from 1954 to 1976. General Guillaume-Henri Dufour, depicted on the obverse, was a 19th-century Swiss military officer and prominent figure in Swiss history, reflecting Switzerland's tradition of honoring national heroes on currency. The choice of the alpine silver thistle on the reverse connected the note to Swiss natural heritage and mountainous identity during a period of economic stability in post-war Switzerland.
The obverse presents General Guillaume-Henri Dufour (1787–1875) in formal historical dress with curled hair, depicted in profile within an ornate oval frame featuring elaborate scrollwork and decorative cartouches. The composition is framed by the trilingual institutional text of the Swiss National Bank, with the denomination '20' positioned prominently. The reverse features the silver thistle (Carlina acaulis), an alpine wildflower native to Swiss mountain regions, rendered in fine detail as the primary design element positioned at left-center. A geometric circular cartouche containing the denomination occupies the center-right area. Both sides employ multi-colored guilloche patterns in red, green, yellow, pink, and magenta tones overlaid on a blue and purple base, creating the characteristic security architecture of this series.

Intaglio printing (engraving) executed by Orell-Füssli (OFZ) of Zurich, the official Swiss National Bank security printer. The visual evidence of fine line work, elaborate guilloche patterning in multiple colors, and the exceptional clarity and depth visible in the portrait oval and thistle engraving are characteristic of traditional intaglio techniques. The multi-layered colored security printing, achieved through successive impressions, was a hallmark of Swiss banknote production during this period.
This note is identified as Pick P-46h (1960 issue date), representing one of at least eight catalogued variants (P-46d, P-46f, P-46g, P-46h, P-46i, P-46r, P-46t, P-46u, P-46v) within the broader 20 Franken sixth series. The variety designation likely reflects differences in signatures, date ranges, or security features across the series production period. The serial number prefix '23P' indicates Series 23P. No specific rarity markers (overprints, commemorative issues, or signature variants) are evident in the visual analysis provided.
