Man I love this spread!
This is a map of the grotto as drawn up in 1950 by Albert Anavy. It only represents half the grotto, as it's only in 1954 that Sami Karkabi reached the very end (I am by the way going to meet this wonderful gentleman so he can double-check the info in the book
I'm so awed.) The main expeditions and how far they reached are represented with the little flags. The geological features mentioned in the book are shown as well, but in reality there are dozens of them, all with exotic names.
The grotto started getting really famous in the 50s, and features on our 1-pound note (now a rarity, but I happen to have kept a handful of now-defunct notes form my childhood) as well as stamps form the period (these are from my collection as well).
Other than the text, which was added in InDesign, the map is shot as is, including the note and stamps. I textured a piece of grey canson, cut out the cave and glued it over layers of mulberry paper (double blue for the water, blue and yellow for the green outside). Featured were painted in with acrylics. The flags were printed and attached to matchsticks, stuck in polymer clay bases. The note and stamps were simply placed over it for the shoot, and I tried different placements for them.
