Vase au miroir by Louis Valtat is a still life painting that features a vase filled with flowers placed in front of a mirror. The colors are vibrant, with rich reds, yellows, and greens that bring the flowers to life. The mirror reflects the vase, creating an interesting interplay between the objects and their reflections.

The background is softly blurred, allowing the viewer to focus on the vase and its contents. The painting is executed in oil on canvas, a medium that allows for rich color and texture. Valtat's brushwork is loose and expressive, typical of the Impressionist style. The dimensions of the artwork are approximately 60 x 80 cm, making it a medium-sized piece that invites close viewing.

The use of light and shadow enhances the three-dimensionality of the vase and flowers. Louis Valtat was a prominent figure in the French Impressionist movement, known for his colorful still lifes and landscapes. Vase au miroir reflects his ability to capture the beauty of everyday objects with a fresh perspective. An interesting fact about this work is that it exemplifies Valtat's interest in the effects of light, which he explored throughout his career.

This painting is housed in the Musee d'Orsay, a museum renowned for its collection of Impressionist art.
