Peonies Gunnar Gunnarson Wennerberg (1863-1914)

The picture has something of this: flower, leaf, nature, flora, pastel, floral, bright, garden, decoration, bouquet, card, rose, beautiful, petal, summer, tree.
Perhaps it’s a painting of pink and white flowers in a vase on a window sill with green grass in the background and a green grass field in the foreground.
