Many thanks to @ruedigerzinke for sharing a photo of Keanu during his visit to Goetingen on twitter. The photo was posted today but I am not sure when it was taken.
Many thanks to Rosanna Pavia for sharing her selfie at JFK on FB and to @Nina_0715 for tweeting the link. The photo was posted on December 8 as he departed for Rome.
Note: His tee shirt in this photo has a rounded neck and the tee that he was wearing in the other airport photo that was posted on Dec 14 had a V neck so that photo was not taken on his arrival in Italy from the states.
