This is an old one, this poster is hanging on the wall of the SciFabLab.

I made it for the Olivetti exposition that we hosted back in 2014 where  many old typewriters and old electronic devices were exposed.
We were honored by the presence of our special guests Gastone Garziera and Giovanni De Sandre, who entertained us with the anecdotes and technical information about the first desktop computer, the Olivetti P101. These two amazing men were part of Perotto’s team, It happened in 1965 when they realized the first desktop computer of the world. 

The designer? Mario Bellini, of course!
