An alphabet (Aa–Zz plus exclamation mark) designed by Alex Stocker and Hans Gruber and reproduced in the first volume of Lettera (1954) under the name Zürich.

An (unauthorized) phototype adaptation appears in a Lettergraphics 1968 catalog as Astrid, with added numerals, punctuation glyphs, and wide alternates for ‘f’ and ‘t’. Shown in Castcraft’s Encyclopedia of Phototype Styles (1978) as “Aggie (similar to Astrid Solid)”.

Digital versions include OPTI Aggie Solid (Castcraft, 1990) and URW Aggie (URW++, 1999). The former includes the original narrow forms for ‘f’ and ‘t’ as alternates.
