Vintage 1966 rye pottery mug celebrating the Commonwealth games opening by Queen Elizabeth 11 amazing condition very collectible nice decorative item 13 1/2 cm tall 10 cm round 
Queen Elizabeth II attended the 1966 Commonwealth Games, which were held in Kingston, Jamaica. She officially opened the Games on August 4, 1966. These Games were particularly notable as they marked the first time the event was held in the Caribbean and outside the "white Commonwealth."
The tankard you have might have been part of a commemorative collection tied to this event, as it would have been a significant occasion in the Queen's role as the Head of the Commonwealth. It was an important event both for Jamaica and for the broader Commonwealth, celebrating athleticism and unity among member countries. Rye Pottery, known for producing commemorative pieces, may have created the tankard to mark this visit or the Games themselves.
 Commonwealth Games[a] is a quadrennial international multi-sport event among athletes from the Commonwealth of Nations, which consists mostly, but not exclusively, of territories of the former British Empire. The event was first held in 1930 as the British Empire Games and, with the exception of 1942 and 1946 (which were cancelled due to World War II), has successively run every four years since.[5] The event was called the British Empire Games from 1930 to 1950 (four editions), the British Empire and Commonwealth Games from 1954 to 1966 (four editions), and the British Commonwealth Games from 1970 to 1974 (two editions). The event removed the word British from its title for the 1978 Games and has maintained its current name ever since (twelve editions as of 2024).
Rye Pottery in Rye, East Sussex, England has a long history that includes several owners and periods of production: 
 
Cadborough Pottery
Founded in 1793 by James Smith, this pottery used local red clay to make bricks and glazed terracotta. His son, Jeremiah, ran the pottery and became a large hop grower and sheep farmer. In 1840, William Mitchell bought the pottery and began experimenting with decoration. 
 
Belle Vue Pottery
From 1869 until it closed in 1939, the pottery was known as Belle Vue Pottery. 
 
Rye Pottery Revival
In 1947, brothers John and Wally Cole revived the pottery and became known for their tinglazed wares. They wanted to create something different to cheer up the country after the war, and were inspired by 17th century Majolica or Delftware.
