Apple CEO Tim Cook said he saw an iPhone in a 356-year-old painting while he was visiting Amsterdam for a technology festival. He and former European Commissioner Neelie Kroes paid a visit to Amsterdam’s Rejksmuseum, where Cook saw a 1670 painting by Pieter de Hooch called “Man Hands a Letter to a Woman in a Hall.” It does look more like the guy’s checking his email than handing a letter to the woman in the hall. But that’s impossible. Or is it? “It’s tough to see, but I swear it’s there,” Cook said in a chat at the Start-Up Fest on Tuesday. “I always thought I knew when the iPhone was invented. But I’m not so sure anymore.” The iPhone was first released in 2007 when Steve Jobs was still the Apple CEO.
