A: London, England, United Kingdom
Poster produced by the Sheffield Typographical Association, a constituent society of the Northern Typographical Union, in support of the Reform Act 1832. Inside the lower printed border the broadside states that it was "Printed During the Procession." The press at the top center is of the George Clymer Columbian type, on which this poster was undoubtedly printed.
In 1830, the Northern Typographical Union, a federation of small local printers' organizations in England and the Isle of Man, was founded. This may be considered the first national printers' union; however, since labor strikes were illegal in England until 1875, it functioned more as a trade organization and lobbying organization than a union in the modern sense.
