I found this excellent font last night while surfing for old Swiss design books. Alte Haas Grotesk by Yann Le Coroller, is a free Grotesk/Helvetica look-a-like with a soft feel to the edges. The author describes it as a typeface that looks like it were printed in an old Brockmann book. It definitely has that feel to it. I’m looking forward to using this in a design.
