An open version of Roman inscriptional caps, similar to Van Krimpen’s Open Kapitalen. There are alternates for ‘MNR’. Comes with numerals and punctuation, but no lowercase. First cast by Bauer in 1952.
Later adapted by VGC, who added a solid style, see Columna Solid.
The only known digitization of the open style is the unsatisfying OPTI Columna (Castcraft, 2006).
