I checked at home, and scanned the publishing info and attached it. I only have issues from about 1912 to about 1924. The editor/publisher was Jan Rosicky of Omaha. His daughter, Rose, wrote the much-quoted History of Czechs in Nebraska.
The audience was not just from the midwest; letters in each issue were from the eastern US, southwest US, and even from the Czech regions in Europe.
In the attachment, note a typical story on the right about a Mrs. Marie Skrivanek who with her three children, Edna 9, Josef 7, and Anna 5 years old, appear to have arrived on the ship "Neckar" going from Bremen to New York.
