I like that Deke! What was that? It looks like a LP cover...
Hi Rosa, sorry I'm responding to your question so late. For a time in his career, Cabral was associated with the Mexican branch of the Bayer pharmaceutical company.
This item is an advertising pamphlet. Inside, there are stories, poems, cartoons, etc., along with advertisements for various Bayer drugs.
Above I included a link to an album that also has some photos of the interior pages.
I thought I had another Bayer publication with Cabral illustrations, but I am couldn't find it on my first search of the bookcase where I thought it was. When I come across it, I'll take some photos of it too.
