Gill Sans™ Extra Bold was designed by Eric Gill. Gill Sans was first introduced in 1928. Eric Gill studied under the renowned calligrapher, Edward Johnston, the designer of the London Underground sans serif typeface. This influenced Gill who later experimented with sans serif designs, and in due course produced a set of capital letters. Gill Sans Extra Bold is a twentieth century sans serif that has a simplicity of form which does not reject traditional forms and proportions, and gives the face a humanist feel. The lighter weights are highly readable in text and suitable for magazine and book work, whereas the heavier weights are best used for display in advertising, packaging, and labels. Gill Sans Extra Bold Character Set: Latin-1.
