Since coffee was their common interest, Yasuhiro and Tomiko Suzuki started collecting demitasse together after they were married more than 40 years ago. They bought one cup and saucer each month, accumulating a diverse collection of more than 500 sets.

According to the couple, the precise craftsmanship of demitasses makes them particularly charming and attractive works of art. Often painted with intricate floral and other motifs, some demitasses were even impractical and made as decorative works of art; Feb. 7-April 5.
