A copy of Frankfurter (Letraset, 1970), outlined with a horizontal stripe pattern that gets darker towards the bottom, not unlike Chwast Blimp A. Origin unclear. Shown as Rock Opera by Formatt [Formatt 1974] and Lettergraphics [Lettergraphics 1976], and as Shady Deal in Solotype’s Art Deco Display Alphabets (1982).
Dick Pape made a digitization based on the latter as DXS Shady Deal (2010, used for sample).
