Brown leather lady's book contains pocket, folds, tucks, flaps and a secret place to store the world's deadliest harpoon point. Map route, code store, ticket holder. Likely to be required at a moment's notice when the adventures begin. (Supplied therefore with a linen thread loop on the binding, to hang it on the bedpost overnight.)
Strap it to your camel, move on. Maps fold out. Map pins included.
Choice 3: Requires purposeful lady traveller, scholarly and intrepid, familiar with the Ritz, but not too effete to strap themselves onto a camel.
