These azulejos, especially the top example, were at one point de rigueur in every Portuguese household. Unfortunately I’m talking about the 1980s, when someone decided to copy the pattern, straighten it, and print it onto cheap, thin, crappy tiles with rounded edges. They were used everywhere, from bathrooms to kitchens to whole facades and represent the 80s developments at their worst. Seeing these today, though hand-painted and beautiful, still makes me shudder a bit (but not for long).
They can still be purchased (the nice, handpainted variety), but maybe one day they’ll be affordable and we will be able to use them in schools again.
