101 modern nautical charts.

Various sizes, various conditions (with handwritten notes of which some are in Japanese, 1 corner missing).

Huge collection of charts with survey results from the respective National Hydrographic Offices of Brazil, New Zealand, Australia, Canada and the U.S.A. It includes 13 maps drawn up by the "Marinha do Brasil, Hidrografia e Navegação", 9 by the New Zealand Hydrographic Office, 14 by the Australian Hydrographic Service, 3 by the Canadian Hydrographic Service, 20 by the United States Hydrographic Office or by the later Naval Oceanographic Office and 42 by the U.S.A. Department of Commerce, more specifically the National Oceanic and Atmospheric Administration (NOAA). It is for political reasons only that this last scientific and fisheries agency is housed in a cabinet department devoted to promoting U.S. trade and economic development. Quoting Barack Obama: "The Interior Department is in charge of salmon in fresh water, but the Commerce Department handles them in saltwater. If you're wondering what the genesis of this was, apparently, it had something to do with President Nixon being unhappy with his Secretary of the Interior for criticising him about the Vietnam War. And so he decided not to put the NOAA in what would have been a more sensible place."
