Selling this Interesting small old storage Jar as per the photos

I do not recall where I got this from but it is possibly a piece of Tek Sing Chinese Shipwreck pottery.

Appears to be a food storage jar and from the decoration, the base and glazing it looks to be very old. 

There is a faint bluish character mark to the base.

It stands 12.5cm tall and at its widest point is also 12.5cm across.

Please view the photos closely to form your own opinion.
