Designed by Karl-Heinz Domning for Berthold Fototype in 1972 [Berthold 1982], Umbra 27 is similar to West Barnum Ultra (Photo-Lettering, 1967), but has unbracketed serifs and some other small differences. No lowercase. Also shown as Umbra 70 [Fürst c.1976] and as Umbra No. 57 [Phil’s Photo 1985].
Bolster (Denis Masharov, 2011) might be based on Umbra 27 (or the same historical source), but has less contrast, wider counters, and several differences in the numerals.
