Designed by Marty Goldstein and C.B. Smith for VGC in 1973. Initial weights were Thin, Plain, Heavy, and Fat.

Fotostar offered 2″ film fonts under the name Sun. TypeShop created the first digital version and Elsner+Flake licensed it under the name Digital Sans.

Canada Type released Sol Pro in 2010 with “optical improvements to the original design, more weights [5 weights in 2 widths], italics, small caps, biform shapes, alternates, and extended language support.”
