A very fine and unusual celestial globe issued in Stockholm for academic and institutional use, originally priced at 118 Kr (of which the government paid 20). The globe was designed to be half-filled with ink or litmus coloured water, to show the selected regions horizon; the water could be drained and replaced through the valves. This example is the last of 50 made.
