The only professional bookbinder's organization in the US is the Guild of Bookworkers. Every third year or so they organize a juried national exhibit that travels around. I saw the current exhibition recently at North Bennet Street School in Boston and here's some close-ups. I'm staying away from commentary on the designs but instead will focus on the details, the beautiful details!
Apologies because most of the photos aren't good -- it's not ideal to take photos from the phone and through acrylic cases. So if you'd like to see all the selections, in nice photos and with their artist statements, order the GBW catalog. And for those in the Boston area, there's a free reception this Thursday, 7/21, at 6pm.
Golly these photos of end caps / end bands / edges really suck.
Sorry, but it was the best I could do!
