  Title: Chicago Star
  Passage: The Chicago Star was a weekly publication, founded in 1946 and financed by Trade unions.  The board of directors were Ernest De Maio, Frank Marshall Davis, William L. Patterson, Grant Oakes, and William Sennett.  Davis was the executive editor, Sennett the general manager, and Carl Hirsch managing editor.  Howard Fast was a columnist, and Rockwell Kent a contributing editor.  In an introduction to a book about Davis, John Edgar Tidwell indicated that the first issue was launched on July 4th to "[wrap] itself in the holiday's symbolic meaning."

  Title: Michael Abramson
  Passage: Michael Abramson (1948–2011) was a Chicago photographer who produced a large body of artistic and commercial photography.  He earned a Bachelor's degree from the Wharton School of Business, but his life took a different direction when he was accepted at the Institute of Design at the Illinois Institute of Technology in Chicago, and subsequently earned a Masters in 1977.  His thesis, "Black Night Clubs of Chicago's South Side," was a reflection and analysis of the photographs he took of patrons and performers in nightclubs on Chicago's south side during the mid-1970s.  Abramson's work has often been compared to the 1920s Paris photographer Brassaï (1899-1984).  Many of Abramson's south side prints were later published in a photography book / 2 LP record set entitled "Light on the South Side" (2009), by Chicago music recording company Numero Group.  The collection of music featured on the LPs are blues songs by mostly Chicago recording artists, and reflect what was actually playing on the jukeboxes in these clubs at the time.  A slideshow was created using Abramson's photographs and the music from the LP.
