President Barack Obama’s re-election campaign is asking artists to design promotional posters that convey a message: “support American jobs.” The brutal irony for artists, however, is that they will receive no payment for their work. The campaign, which has $61 million on hand, will reward only the three artists whose work is selected for use. The compensation? A copy of their artwork, signed by the president. The Graphic Artists Guild isn’t pleased with the ask. On Saturday, the guild issued an open letter to the campaign voicing outrage over what it called a “shameful” competition.
