Artist Jonathan Yeo was moonlighting in New York last week. In his day job, he works as a celebrated painter, creating portraits of people like the late Dennis Hopper, Prince Philip, Tony Blair, and George W. Bush. (In his portrait of the latter, the president looks like the pinnacle of conservatism until, on closer inspection, you see that his face is constructed from a mélange of pornographic images.)

As a side gig, however, Yeo works as a curator for Soho House, the private members’ clubs, using his artistic prowess and relationships to build what is fast becoming one of the most eclectic collections around. Over the course of four days, Yeo hit the various art fairs going on simultaneously in New York City (the Armory, Pulse, Volta, Independent) and, with his iPhone, catalogued what caught his eye, both good and bad. —Susan Michals
