Classic safety posters
Posters have long been used to communicate safety messages to workers in industry, and to the general population (often in a fairly paternalist manner). The design of some of these posters is very striking; we include a few examples in the gallery below.
Unlike the rest of the material on this site, the concepts pages are sometimes written in a slightly provocative manner (though we try to separate the facts from the opinions). Your comments are welcome by email, or via Twitter.
