The art of covering different surfaces with tile shards to compose a mosaic is called trencadis and it was widely used by Gaudi and his followers. So far so good. What is it with souvenir shops and 'artists' in Barcelona that tend to evoke such technique by using elements so irrelevant to Catalan culture as flamenco dancers or bulls. This is as ambiguous as pretending that Catalans go around wearing Mexican hats.
