The Royal Cauldon 

Seder Plate

designed by Eric Tunstall 
in what I believe was the 1950's / 1960's
Please see if you agree

The artwork & written detail makes this 
one of the most outstanding 
Seder Plates I think

All the pieces carry the same back stamp

It's a large centre piece & the plate is a fraction under 16 inches in diameter

Condition: I think it would be hard to find a better example
- It has the usual glaze crazing that you'd expect
- The only blemish is a little staining in the Bitter Herbs bowl
