1920s Celluloid Union Jack George V1 and Queen Elizabeth, the Queen Mother Pin

A little celluloid bow in the Union Jack colours and a round tin frame containing a picture of a young King George V1 and his Queen, Queen Elizabeth, the current Queens mother.

Maybe made to celebrate their wedding on April 26th 1923.

A simple pin on the back, to be worn on a lapel.

The whole thing is 3.5cm tall and in very good condition, found in an old warehouse.
I also have 1 with a bit of a mark - see 3rd photo - cheaper !
