4 floral lithographs 1900

Sublime series of four floral lithographs. From the book "modern decoration by the plant, " published around 1900. Pastel to vivid colours; peony, buttercup, gladiolus, and ivy. The frames must have been custom-made, as they are not all the same size. Stained brown wood. One of the frames, that of the buttercup study, has a broken corner at the bottom right, visible in the photos, stabilised but still present. The frames measure approximately 37 by 26.5 cm. In Art Nouveau style, the drawings were created by the decorative painter E. Mulier. Very good overall condition of the plates, a beautiful set of four on a wall.
