A procession float with two chromolithographic prints, created in the 19th century, most probably belonged to the St. Joseph's brotherhood of carpenters, who at that time took care of the altar under this invocation, as evidenced by the image of this saint appearing on one of pages of the work. Procession floats are decoratively framed paintings or statues adapted to be carried in processions, therefore they are bedded in the bases, in which rods are inserted.
