Collective entry for adaptations of an unnamed alphabet originally designed in 1930 by W.A. Dwiggins for the cover for Paul Hollister’s book American Alphabets.
Lettergraphics had a film type version named Fast Lady D [Lettergraphics 1976].
Matt Desmond expanded Dwiggins’ alphabet into a full typeface as Dwiggins Deco (2009, used for sample). John Wollring made another interpretation named Dwiggins Initials KK (2012).
