Vintage high quality Still Life Painting

Vintage still life painting on canvas board. Unframed.
This is an original artwork signed "Dean" and is dated 11/82.
It has nice detail, you can see the shadow of the teapot on the wall and the cup/saucer reflected in the teapot.
Beautiful muted tones, would be great in a kitchen.
