Production Type is a French type foundry, imagined and created by Jean-Baptiste Lev/u00e9e. It develops typographic characters available for purchase, as well as made-to-order fonts for private customers (Lib/u00e9ration, Renault, LVMH, Vanity Fair...).

To celebrate the foundry's 5th anniversary, Production Type is organizing in 2019 an exhibition dedicated to it in Paris, entitled Signals, which also includes a photographic exhibition by Julien Leli/u00e8vre.

Avant Post was asked to work on the production of three photographic visuals for the exhibition's communication, and designed a series that illustrates three types of signals: sound (with alarm sirens), radio (with an antenna-related game) and visual (featuring a rotating light).
