Art nouveau grew from the Arts and Crafts movement, art nouveau shared the same belief in quality goods and fine craftsmanship but didn’t mind mass production. It was characterised by intricate linear designs and flowing curves based on natural forms and botanical research. Art nouveau also features a lot of the female form in a pre-Raphaelite pose with long, flowing hair.
The birth of department stores was one factor of the Art Nouveau movement. Department stores mass produced item that they guessed people would buy and it was the start of mail order catalogues so companies need to advertise their stock to sell it. The second factor was the introduction of printing. Colour printing had became a lot cheaper and large rolls of paper were now being produced for the lithography machines. This created continuous printing for mail order catalogues and advertising.
