Angel Alley, A, A
The "A"s are certainly the anarchists' 'A' symbol but we don't understand what the hands signify. The gesture shows the thumb and first finger formed into a cup shape, so not the "hand rock" horns. Any ideas?
This cast-iron roundel is one of 22 - see Bowler's page for more details. This one was not in the original 1995 group, but was installed by December 2016.
