The Tribune described its technology as “modern in every detail,” including a “40-page Rotary Press which can print 30,000 complete newspapers per hour—controlled by seven master stations to stop and start the massive press by simply pressing a button—this is progress.” The ad encouraged readers to visit the Tribune building at 526 S. 16th Street: “Try to get down Thurs., August 27th, to see the big Edition [Elks and ‘Progress’ special edition] come off the press.”
