The “Corona Four KEYBOARDS 1928” handbook was part of a dealer’s sales equipment, including dozens of keyboard arrangements for languages and specialty purposes. The company distinguished “type face” as the style of the font — Pica, Italic, Micro, Elite, Gothic, and Pin Point-Gothic Combination — and “keyboard” as the language or purpose.
“The salesman should point out, however, that practically any combination of characters can be made up into a special keyboard,” the document states. But, the company explains, the “salesman should use every reasonable effort to dissuade the customer from ordering unusual keyboard arrangements,” as the customer might find resale difficult.
The booklet, available here as a PDF download (57 mb), describes nearly 100 typefaces. Many of the foreign-language keyboards simply include special accents, but several display foreign characters. Several keyboards are for specialty purposes.
