I thought that the Anarchy symbol was a 1976 creation.
Apparently he was ahead of his time.
Or, if we apply the Ty Webb method and Google First, then ask second, we get this in regards to the Circle A as used by Anarchists:
History of anarchist usage
The first recorded use of the A in a circle by anarchists was by the Federal Council of Spain of the International Workingmen's Association. This was set up by the freemason, Giuseppe Fanelli in 1868.[11] It predates its adoption by anarchists as it was used as a symbol by freemasons amongst others. According to George Woodcock, this symbol was not used by classical anarchists. It was first used by a small French group, Jeunesse Libertaire ("Libertarian Youth") in 1964. Circolo Sacco e Vanzetti, youth group from Milan, adopted it in and in 1968 it became popular through out Italy. From there it spread rapidly around the world.[12]
And now by further application of the Sherlock Holmes method, we can now deduce that the guy in that picture is probably French or Italian, and he just happened to be in Chicago, and decided to help out with the protests, and that the jewel is hidden in the last remaining bust of Napoleon.
