Crown Staffordshire vase in royal blue.  I am guessing at the age - noting that the bottom mark indicates "England".  Whereas there was no "Made in ..." mark before the early 1900s, and the "Made in England" mark was introduced after the 1940s.
 
The mark of "1801" on Staffordshire pieces indicates when the Minerva Works were established.  The works then came into the hands of the Crown Staffordshire Porcelain Co.
 
It is in beautiful condition and measures 9" high.
