This poster advertises the three font families within the Base typeface, all of which take the numeric portion of their names from their point size on a screen. At this time, the way letters rendered on a screen was not necessarily how they appeared when printed. Typefaces like these were meant to solve that problem by creating more parity between the two. The three font families are presented in the upper-left area of the poster, each of which is offered in regular, italics, bold, and bold italics. Base-12 has both a serif and sans-serif variation, resulting in a total of 12 unique typefaces.
