Ocean Passages Of The World - 1923 "The Bible of the Sea" This book is rare not only due to its age and nature, but also that it was captured by the German Military as a secretive document. Both the book itself and its extra documents and maps have the Stamp of the German Secret Service, with the book also including a stamp explaining that it is a "Secret Document under the laws of the 24th April 1934" captured from the British. The front cover is separated from the book, but the pages themselves are in good condition, as per photos. The documents with the book are a supplement from 1931 and 1939, and 5 maps : ~ The World - Winds ~ The World - Ocean Currents ~ Indian Ocean - Steamship Routes ~ The World - Sailing Ship Routes ~ Atlantic Ocean - Steam Ship Routes All in good condition. Was given to me by a German Sailor As per photos
