First button showing a red brick inscribed "Rochester, N.Y." has additional text "Baustein Fuer/Labor Lyceum." This lyceum was founded in 1897 in Rochester by local unions and socialists. They presented speakers, papers and debates on topics ranging from trade unionism to child labor and academic freedom. In 1911 the mayor, upset with such programs, expelled the lyceum from City Hall. The organization built a new headquarters in 1912, using the fundraiser button, which provided space to socialist organizations and housed radical unions such as the Amalgamated Optical Workers and the Brewers.
