Sake cup with maki-e design of Shinagawa

Shinagawa coast was a famous place for shell-gathering, often painted in Ukiyo-e wood prints as well as in “Edo Meisyo-zue (Guide to Famous Spots of Edo)”.
This vermilion lacquered wine cup is considered to be one of the famous landscape series cups, given from the shogun family.
On the interior surface, a grand view of the Shinagawa coast is depicted in hira maki-e (flat sprinkled metal). Mt. Fuji and sailboats in the offing are visible in the distance. The Tokaido highway along the coast is lined with shops whose roofs are shining by kanagai (foil inlay).
It bears an inscription that reads ‘梶川作 (by Kajikawa)’ on the exterior surface.
