Hello,
my apologies if i have posted this twice but i am new, i got this 10cm tall blue and white vase and was wondering if anyone can help in identifying the 4 character mark on the base which is within larger double blue circles. The previous owner tried and gave up so can anyone out there with greater knowledge help me at all ? Its unusual in that it has the fingermarks on base where it was held to be dipped in the glaze apparently. They thought this was cute and showed the potter was trying to personalise it ?
