Doctor Strange: 7 MCU Connections You Might Have Missed

4. Queens

Stephen Strange's lush New York apartment is littered with dozens of expensive items and furnishings - most prominently, a majestic, glossy-black grand piano.

Just above the piano's keys - and only if you're paying close attention - you'll notice the name of the manufacturer, Steinway & Sons. Steinway & Sons is a renowned American-German piano company that produces those musical instruments and ships them worldwide. The company has two main factories; one in Hamburg, Germany, and one in an area that a lot of Marvel fans will recognise; Queens.

This could be a nod to Spider-Man's home borough of Queens, New York - last seen in Captain America: Civil War in the scene between Robert Downey Jr's Tony Stark and a rather flustered Peter Parker.

Parker traditionally lives in Queens and that hasn't changed in the MCU, and it's ironic to see that such a pricey item was manufactured in an area that features the Marvel universe's most humble, modest hero.
