Thanks, Georgia. These photos are by Megan Mock so you can ask her :) Actually Sara and I did make a prototype of a book back in 2009 but we ended up not producing it. And see our Exhibitions page for a small Herbarium book we did at our Berlin residency.
When I saw that first photo, I thought someone had built a little house for the top of the cactus. But now I see that the tip of the cactus is just reaching the box. Maybe that box is keeping the cactus from tipping over! Or maybe the cactus is giving that box little cactus kisses! Haha, that’s what I should call it when I kiss my wife or my baby with my stubbly beard–cactus kisses!
