27 APRIL 2013
 
On 19 April, six-year-old Madison Grimm, of Burbank, South Dakota, was announced as the winner of the nationwide Jr. Duck Stamp Contest.

A week later, she was disqualified as the winner.
 
From an announcement by the USFWS:

At the National Junior Duck Stamp Contest, held on April 19 in Shepherdstown, W. Va., a panel of five judges selected as the winner a painting of a single canvasback by Madison Grimm, 6, of Burbank, S.D. Following the contest, concerns were raised by parents and teachers about the authenticity of the work. The Federal Duck Stamp Office investigated and learned that the painting had been transferred, which is inconsistent with the Junior Duck Stamp Contest rules.  On the advice of the Department of the Interior’s Solicitor’s Office, Grimm’s painting was disqualified and [runner-up, Peter] Coulter was named the contest winner.

Coulter, 17, of Washington, Missouri, painted a pair of Snow Geese.
