The wall art was commissioned by a coffee shop "King Coffee Service" that occupied the building before the coffee shop "Es mīlu kafiju" took its place. The artwork's style resembles the look of charcoal on the wall although it is created with long-lasting color. The artwork touch upon the story of coffee's origin and its road to Europe. As it is known the coffee culture in Europe originated in Italy, Venice in 1645 and it spread throughout Europe and the new world via merchants and trades.
