Seems like my 3 hour delay was worthwhile. I was glad to see a wonderful display of three colour gum bichromate over cyanotype prints by Sarah Van Keuren. In all, there were 10 framed 16x20 prints in an exhibition she titled "Rooted Protagonist"; all nature. Really nice to see some historical process prints on display. If you're passing through Philly airport, it's in the hallway to gates F24 to F39. Regards, Art.
