In the late 1960s, IBM was one of the world’s pre-eminent corporations, employing over 250,000 people in 100 countries. While Paul Rand’s creative genius has been well documented, the work of the IBM staff designers who executed his intent outlined in the IBM Design Guide has often gone unnoticed.

I have always loved the design work created for Olivetti. The colourful midcentury designs by Italian designer Giovanni Pintori, the minimal typographic poster by Swiss designer Walter Ballmer and my personal favourite the 1959 poster for Olivetti designed by Herbert Bayer. I recently found out Triest Verlag released a new book, Visual identity and branding at Olivetti which contains further work by Xanti Schawinsky, Renato Zveteremich, Ettore Sottsass, Hans von Klier, Egidio Bonfante and Walter Ballmer.
