Hmmm, here's Nike's press release on it:

"
Limited edition, individually numbered artwork prints of the shirt will be created and sold, with a number available to purchase at Nike Phenomenal House at the Sorting Office. London's Phenomenal House will open its doors to the public from May 26-31 for a unique, diverse and action-packed celebration of fearless football and London’s love of the game.
The shirt itself is not for sale. It will be on display at the Phenomenal House from May 26-30, then at NikeTown London from May 31, before moving to its permanent home in the Arsenal Football Club Museum from June 30."
They must have switched "prints" with "jerseys"
