When manufacturers take a new car out for actual roadtesting, they try to obscure it with fake body panels, blackout tape, etc. to throw off the spy photographers.
For strollers, though, the strategy is shirts. Mike Richards, the only person not stunned into silence by this man's shirt, gets credit for New York's first documented Stokke Xplory sighting. It was Fourth of July weekend, in SoHo. The Xplory is a grey market model, presumably brought over with the band equipment.
