Oskar sets out - with a single coin - to find the perfect gift for his mother. And he spots it at once: a beautiful yellow rose. But when he meets an artist, Oskar trades the rose for a paintbrush. And when he meets a conductor, he trades the paintbrush for a sheet of music... The bustling streets are full of interesting people and delightful possible presents, and Oskar trades one gift for another, and another, and another! But what he finds by the end of the day is even more precious. Simple kindness is at the heart of this enchanting, gloriously-illustrated tale.
