Tie pin of Great Bitter Lake Association. Gold-coloured metal with an oval plaque fixed to the pin. This bears a diagonal pale blue stripe with white borders. Another oval plaque is suspended from a short chain. This is enamelled with a dark blue background on which is a yellow anchor with the numbers '1' and '4' on either side of the shank, 'GBLA', below. The Great Bitter Lake Association was a social club for officers and men of the fourteen ships trapped on the Great Bitter Lake (the widest part of the Suez Canal) after the canal was blocked during the Six-Day War in 1967. They were not released until the canal re-opened in 1975.
