Post-American settlement clothing

This is a great example of changes in Native American art after the U.S. took over Native lands.  This shirt that was made by a Native American has U.S. regalia all over it.  Stars and stripes bands down the arms, Blue stars placed all over the shirt and the giant U.S. flag chest piece.  The purpose of making this may have been to sell it to U.S. citizens or may have been the product of direct or indirect pressure from the U.S. government to suppress native culture in order to assimilate them into white U.S. culture.
