It is a comparison of individual characters in Akzidenz-Grotesk, Folio, Helvetica, and Univers 55.
Helvetica's strokes are characteristically cut either horizontally or vertically. This is particularly observable in the t, r, and C.

"Helv", afterwards known as "MS Sans Serif", is a sans-serif typeface that shares several key characteristics to Helvetica.
