Liechtenstein’s 9 November 2026 programme includes three stamps marking 100 years of the Personen- und Gesellschaftsrecht, or PGR. The CHF 1.20 design depicts the law book, while CHF 1.90 and CHF 2.50 designs honour Emil Beck and Wilhelm Beck respectively. The operator lists the stamps as gummed.

The legislation entered into force on 19 February 1926. The two Becks prepared it over almost four years before submitting it to parliament, which adopted it on 5 November 1925 largely unchanged. The issuer connects the law with the development of Liechtenstein’s corporate structures and financial economy.
