I love the collages of artist Kurt Schwitters, always have. And the more I look at them, the more I wonder how much he may have been influenced by postings on billboards seen in his youth. Much more prevalent in Europe than in the USA. Layered, overlapping, ripped off, perhaps only partially. Look at the assemblage on this billboard here in the south of Spain. Except for the little bit of graffiti, this collage with its text, its strong colors, its own geometry... it could easily be something Schwitters might warm to. And given that the posting announces a strike (huelga), he might like it even more.
