This rare type specimen book, published by the Nebiolo foundry, is from the private archive of Enzo Biffi Gentili, director of the MIAAO (International Museum of Applied Arts) in Torino. If this timeline is correct, I figure the book was published sometime between 1962–66. (Estro and Eurostile are shown, but Magistier, Oscar, and Forma are not.)
Estro appears on the cover. Recta is used for labels throughout the interior.
