This is an optical illusion for sure. You are looking at a paper water garden (complete with koi fish!) in Ray Marshall's magnificent book, Paper Blossoms. It was given to my mother and she brought it along with her to Florida so that they could have flower arrangements any time they wanted.
Book is contains 5 perfect pop-up bouquets. It is a masterpiece, really. I can only imagine the vision and determination it takes to get an intricate book like this produced. Each morning during my visit, I come out into the family room and see a bouquet open on the table. This lily pond is a favorite.
On this 4th day of the 12 Days of Valentine's Day, go buy some Valentines and send them off to those who would love a surprise in their mailbox.
