This is from the famous Ca Mau shipwreck, which led to a huge sale in Amsterdam at Sotheby's.   This is a lovely saucer with no major damage... a couple of tiny blemishes and specks on the front..a grit on the rim....this is a lovely example.... There are a few pinpricks on the base.  It has just under a 4.5" diameter.  It rings.  Please do not hesitate to contact me with any queries - and multiple purchases do lead to postage reductions.  I am listing a lot of pieces from this period so please check my listings.    I will also only send any item which sells for over £50 by recorded or special delivery in the UK or by internationally signed for with insurance and tracking overseas.  This protects the buyer overseas fully in case of loss or damage. Multibuys do lead to reduced postage
