The script used in “Hand Painted” is also a bit different. UPDATE 2/20/12: Even more backstamps have been added to the list! We are sharing a small list here (with pictures) of the ones we have come across in our Nippon journeys. We hope this helps those out there looking for this information quickly.

By using the information below you can find the date a design was registered. Remember this date is just when the design was registered.
In the Sorgenthal period (1784-1805) an additional year mark was introduced.
From 1783 onwards the year mark was impressed alongside the factory mark.
Between 17, the Vienna Porcelain pieces destined for the Austrian court were distinguised by a special (Bindenschild) shield mark in underglaze blue.
Inferior quality pieces or seconds were marked with either a red or green ‘A’ over the underglaze blue mark or by two intersecting nicks over the mark.
