The background shows sidewalk tiles - "rajoles" - that pave the sidewalks throughout Barcelona. They were designed by architect Puig i Cadafalch for the entryway of a home. Since 1915, they have been used by the city to pave sidewalks, and have become emblematic of the city. One of the city's most famous chocolatiers, Enric Rovira, produces chocolate bars in the shape and design of these tiles.
