During the late 1970s, when oil was still “hot”, the Smurfs were called upon by BP to promote a lot of their products. Some of the material seems to have been the result of a blind tracing experiment, some of it was actually pretty good. As was the case with much of the Smurfs advertising illustrations. Various campaigns were set up all over the world, from Australia to Germany, and in some areas they still pop up once in a while, even as late as 2017 in New Zealand.
