Beechams-The Flag of Health

Supplied in a card envelope, this small 26 piece cardboard puzzle features twelve flags of the British Empire and promotes Beechams Pills as being worth a guinea a box.
The puzzle is thought to be of c1930's origins and the presence on the list of flags of the I F State denotation for Ireland implies pre 1937 production, when a referendum brought the Irish Free State to an end.
