How does Pioneer Woman elucidate its Derivative works?
There have been several notable works of sculpture proposed or produced in the years following the unveiling of the Pioneer Woman based on it.  The first one was the Kansas Pioneer Woman Memorial.  A competition by the Pioneer Women's Memorial association was held and, as in the competition for the Ponca City statue, Bryant Baker was the winner. A Kansas critic at the time pointed out, "There is a striking similarity in the appearance of the two works despite many actual differences."  However this version of a Kansas monument was never completed.  In 1937 the Pioneer Women's Memorial association presided over the unveiling of the Kansas Pioneer Memorial by Kansas born sculptor Merrell Gage, a work very different from Baker's.
In 1959 a 36' tall fiberglass sculpture by Gordon Shumaker was produced to commemorate the first 100 years of the Minnesota State Fair.  It stands in front of the Pioneer Building.  Like the Ponca City statue, it depicts a bonneted woman in ankle length dress striding forward, and like its predecessor, she holds a large book/Bible in her right crooked arm as well as carrying a large bundle on the same arm. At 36 feet tall she more closely approaches the monumentality that Marland was originally seeking for his work.
Hardship and Dreams was the title of a sculpture by Dorothy Koelling (1913-2004) unveiled in Wichita, Kansas on June 28, 1994.  A newspaper article at that time described the work as being, "inspired by the monumental 'Pioneer Woman' in Ponca City, Okla." Koeling's six foot tall statue depicts the bonneted pioneer woman, carrying a large book/Bible and bundle in her right arm, marching forward with her flatfooted son, whose hand she holds, next to her.
