From about 1400, there began a "visual revolution that inundated Europe with images during the fifteenth century" (Field) as the woodcut technique was applied to paper, which was now manufactured in Christian Europe, instead of being imported from Islamic Spain. In the 15th century, the great majority of these images were religious, if playing cards are excluded. They were sold at churches, fairs and places of pilgrimage. Most were coloured, usually crudely, by hand or later by stencil. One political cartoon relating to events in 1468-70 has survived in several different versions (many from years later). Old master print is a term that at this period includes popular prints, but later is restricted to more expensive and purely artistic prints.
