About The inspiration for this font came from a poster for an Austrian trade show from the 1920s, credited simply to Wasserman. The “lightning bolt” uppercase S is an interesting study in contrast; however, for those unimpressed, a more sinuous lowercase s is included.
The commercial font is “new and improved” over the freeware version, with expanded character set and improved kerning, so you get what you pay (or don’t pay) for.
