The base has a “min yao” Yongzheng seal mark in overglaze iron-red enamel, but the cup probably dates to the later 18th Century. The decoration is in overglaze enamels and the rim has a faint brownish wash. Although the piece is in very good condition-- no chips, cracks or restoration, the glaze has numerous tiny iron specks, particularly visible on the interior. The footring displays the very white paste often seen in 18th Century wares.
The design is inspired by the well-known, but rare imperial “chicken cups” of the early 18th Century, which were derivative of the extremely rare ones from the Chenghua period.
