The Madison Avenue building is at its end and the Koons exhibit has closed now, so let’s trash it. No, we’re not doing that but I’ll bet your Instagram feed at some point over the last few months might have shown you a selfie taken at “Jeff Koons: A Retrospective”. There were LOTS of shiny reflective surfaces so it was irresistible selfie bait. I did one myself, but I didn’t tag it properly –I guess, as I’m not their demo. Plenty of #KoonsSelfies were taken by youngsters because the Whitney had been passing out cards that instruct teens exactly how to share their love of the Whitney. “KOONS IS GREAT FOR SELFIES” the boldfaced message reads. “Take a selfie and post it on Instagram! Use: @whitneymuseum and #Koons #ArtSelfie”. No doubt this will continue at new Meatpacking District location which opens next spring. Check your Instagram feed, kids.
