The Ancient Order of Froth-Blowers
The 'AO/FB' lettering on this pair of silver cufflinks from the Museum of Liverpool's social history collection stands for the Ancient Order of Froth Blowers.
The Ancient Order of Froth Blowers was a humorous British charitable organisation set up:
"to foster the noble Art and gentle and healthy pastime of froth blowing amongst gentlemen-of-leisure and ex-soldiers"
Running from 1924-1931, it was founded by Bert Temple, an ex-soldier and silk-merchant, initially to raise £100 (equal to £4,829 today) for the children's charities of the surgeon Sir Alfred Fripp.
