Answer: It's probably important to have realistic interpretation because then the artist's audience can actually relate to it.
The role of the artist has change ( if any) may have been the fact that now not only do they speak for themselves, their art now expresses other people's feelings too that can not express on their own.
Art Noveau is portrayed by many women with long hair and floral backgrounds so maybe you could advertise a certain beauty product, like maybe a fragrance with the aroma of spring flowers. Or maybe a new fancy beverage like wine or champagne or something. Hope this helps!!
