When a poor devoted widow asks a rich faithless baker for a bit of bread, she offers to attend the king's wedding mass in exchange for the baker's charity. The baker writes "One Mass" on a scrap of paper and weighs it to see how much bread it is worth. Nothing in the shop, not even the massive wedding cakes produced for the king, exceeds the small piece of paper symbolizing the genuine worth of a mass, much to his and the entire town's surprise. The interior of the book is decorated with luminous old-world watercolour paintings, and gold foil artwork adds a sense of solemnity and spiritual beauty to the story. Since its initial publication, this has been a best-selling children's book. It is frequently adapted into plays for catechisms, used in homilies, and read on YouTube as well as private sites and channels.
