Many typefaces designed with a pen on paper (especially those from the 20th century) were licensed by different foundries, and were later independently digitized by them. Some special characters such as @ or the euro sign, were independently added later. Those “alternate cuts” are different digital versions of basically the same typeface design. They often vary in character set, letter proportions and kerning. Some are published under different names.
Although designed by the Hungarian Nicholas Kis in about 1690, the model for Janson Text was mistakenly attributed to the Dutch printer Anton Janson. Kis original matrices were found in Germany and acquired by the Stempel foundry in 1919.
