Poster "no water in acid"- chadebec

Poster from the 1980s, drawing by bernard chadebec. "no water in acid" this is a poster produced by inrs for safety at work. Fortunately, it served! We removed its protective plastic (yellowed by time); the poster is glued to the original plywood plate, it has some tears and traces of its old frame in places. We think it can be useful, in a kitchen, to remember that you do not put water in the dressing. Poster dimensions: 57.8cm*79.5cm. Plywood plate dimensions: 57.8cm*88cm, thickness: 5mm. (it is unlikely to be able to peel off the plywood poster without damage).
