The Gang’s little bro snapped these off for us as he fanged through Logan Airport (Boston.) He didn’t have time to catch the artist, but after a bit of internet stalking we’ve managed to track the relevant info down; sculptor Chris Williams (website here) – the piece is entitled Seascape…
Anyways, we searched the site and couldn’t find any mention of the gaffer. (But it was ever thus, eh.)
