This fabulous 3D face (tradename unknown) is the “poster child” for runics, a style class with fieldmarks like cupped serifs and the ever-so-handsome R. It may have been rare during the 19th century; the only matching specimen found so far is a numbered “two-line” one shown in the Boston TF catalog of 1860.
It is likely that the punches were produced by BTF’s staff type-cutter, Samuel S. Kilburn [1799–1864], who specialized in display types of this size.¹ Since he was not a designer and Nicolette Gray discusses only one runic (dated 1869), the working model was probably French.
