"The Nile" Fold-Out Map 1930s Lehnert & Landrock

From the internet:
Lehnert & Landrock, Cairo circa 1930’s 10 x 4.5” fold-out map with 12 panels, single sided, in full color showing the Nile as it winds down from Alexandria on the Mediterranean Sea to the damn at Aswan and the Philae-Temple of Isis. An additional inset in the lower left at the bottom of the map follows the Nile further south as far as the Abu Simbel temple and Wadi Halfa (Sudan). Nice details with small rectangular illustrations (about 1.5 x 2” each) showing the highlights along the way. Lehnert & Landrock was a North African photographic studio run by Rudolf Franz Lehnert and Ernst Heinrich Landrock active in Tunisia and Egypt in the early 20th century, noted for producing Orientalist (i.e. exotic/erotic) images. They also published guide maps such as this on for North African tourist sides. They later founded a bookstore in Cairo which still exists today.
