Sailors' Day fundraising button

Circular fundraising badge or button sold during World War Two to support the 'Sailors' Day' appeal. It is made from printed paper between a tin base and celluloid cover.
It is in the patriotic colours of red, white and blue. It features a central white anchor on a vibrant blue background surrounded by a thin red border.
The denomination '6ᵈ' (sixpence) is printed in red block text directly on the upper shank of the anchor, while the text 'SAILORS' DAY' is printed in red capital letters, curved neatly along the white stock and flukes of the anchor's lower crossbar.
The reverse has a metal pin which encircles the edge of the badge before ending in a point which can be pushed through clothing for attachment. There are no maker's marks.
