A typeface with biform alternates designed by Aldo Novarese for VGC. Several sources give a 1973 date, but Sintex already appears in PLINC’s Alphabet Thesaurus Vol. 3 (1971) and was used in 1970. Fotostar’s version was called Hopfen. Similar to Zipper (1970) and Beat Star (1972). Stretto is a digital revival.
