A Chinese export 'Batavian' tea bowl & saucer, Kangxi or Yongzheng

A Chinese export teabowl and saucer, decorated in underglaze blue and with a rich brown 'Batavian' style glaze to the exterior, dating from the Kangxi to Yongzheng period.  Both the teabowl & saucer are decorated with stylised chrysanthemum flower heads, interspersed with butterflies.  The base of each has an underglaze blue mark to the base (possibly the stone chime and halberd mark, shown as figure 3383 in Gerald Davison's handbook of marks, which is a rebus for 'auspicious happiness').  Saucer diameter 9.7cm (3.8"), teabowl diameter 6.9cm (2.7")

Date: Kangxi to Yongzheng c 1710-30

Condition: both the teabowl and saucer are in very good condition with no chips, cracks or restoration.  There is a small amount of glaze crazing inside both the cup and saucer which is purely in the glaze layer, not in the porcelain body.
