I recently read an article on http://www.vignelli.com/ that described the artist Massimo Vignelli who has worked all over the globe in the world of design. Massimo has done extensive work in design ranging from print, to poster, to computer design, and typography. Massimo describes how the text font Helvetica works in design in most scenarios as its easy to read and bold.
In the campaign posters on the site titled “I love typography” Massimo Emphasizes how font types like Helvetica, Times and Bodoni work so well in design.
As you are probably able to tell the font above is solid and solem, not hard to decipher and that is one of the many reasons people like Massimo probably like Helvetica so much.
