The sculpture of St. Joseph, along with the whole high altar, was created in the Cracovian sculpture workshop of Władysław Druciak in 1914. His works are described as an example of historicism in sacred sculpture of the early 20th century. Saint Joseph has been depicted in a traditional iconographic convention, i.e. with Baby Jesus in his arms, intended to show him as a guardian and protector of the Son of God, as well as with a white lily in his hand, a symbol of chastity.
