Olivetti Lettera 22

The Olivetti Lettera 22 is a portable mechanical typewriter designed by Marcello Nizzoli in 1949 or, according to the company's current owner Telecom Italia, 1950. This typewriter was very popular in Italy, and it still has many fans. It was awarded the Compasso d'oro prize in 1954. In 1959 the Illinois Institute of Technology chose the Lettera 22 as the best design product of the last 100 years.

The typewriter is sized about 27x37x8 cm (with the carriage return lever adding about 1–2 more centimeters in height), making it quite portable at least for the time's standards, even though its 4 kg (8.8 lb) weight may limit portability somewhat.

The model was eventually succeeded by the Olivetti Lettera 32.
