Vintage set of three Tengu Guinomi

A fine set of three tengu guinomi in their own presentation box. The Tengu is a common motif and his mischievous nature and both malevolent and benevolent character may be particularly relevant when drinking sake! 

The sake cups are approximately 3cm and 7cm wide, the box is 10 x 5.5 x 29cm. Date is unclear, they could be post-war but are probably at least 50 years old if not a bit more.
