Visual arts are covered by United States copyright law:

"independent creation is permitted.A second work, identical to an earlier copyrighted work, does not infringe, if it is, in fact, independently created. [Of course, the better known the first work, the less likely that an independent creation defense will be believed.]"
The odds of the Young-Rosenast version of the work being independently created are low, considering the time of creation and the proximity of the Featherston Gallery.
Until this changes this article and comment are just whining.
You can't just convert to Socialism on one issue when it impacts you. We live in a right wing capitalist country. Barrak Obama is somewhere to the right of Ronald Reagan.
