Spode New Indented earthenware Soup Plate blue transfer printed with P622 'Lange Lijsen', otherwise known as 'Jumping Boy'. It is also sometimes referred to as 'Long Eliza' although this particular design frequently does not include the jumping boy.
Spode's version is a direct copy of a Chinese design that would probably have arrived in the UK via the Dutch & the East India Trading Company which had been importing a great deal of Chinese porcelain prior to 1800. The original Chinese pattern dates to the K'ang Hsi period of 1700-22 but was still being produced during the Ch'ien Lung period of 1735-96.
The Dutch name 'Lange Lijsen' means 'slender damsel' & when these popular Chinese designs were reproduced in Britain during the mid, & late 18th century & early 19th century on early soft-paste porcelain, creamware & pearlware they became known as 'Long Eliza' & 'Jumping Boy'. 'Long Eliza' very often held a parasol & there was an absence of a jumping boy.
My reference books describe the Spode version as 'fairly uncommon' & of 'middle-period production'; I would guess at introduction c1815. A most interesting example of this Spode pattern is the Leg Bath which can be seen illustrated on both the Spode Museum Trust website & the Transfer Collectors Club website here:
This Spode earthenware Soup Plate decorated in 'Jumping Boy' pattern measures approximately 9.5 inches or 24 cms in diameter & 1.5 inches or 4 cms deep. It is marked to its base with an impressed 'SPODE' & a potter's number together with a blue printed 'SPODE' & a printer's mark. Notice there is no foot rim to this dish.
