I've rarely seen a story with such an embarrassment of riches when it comes to puns. Here are some other post titles I considered:
Last Manet Standing
Show me the Monet!
Everything must Gauguin!
Running out of Degas
Nothing left Toulouse-Lautrec
In this American Interest story, it's the Blue Bloods vs. the Blue Collars in the fight for Detroit's art collection:
"The blue civil war is getting heated in Detroit, pitting blue collar workers and pensioners against the wealthier blue state arts-and-culture set. Reuters is reporting that some union leaders are calling for the liquidation of the Detroit Institute of Art in order to protect pensions."
Detroit is broke. It doesn't have the luxury to look at pretty pictures.
