subame no koya tembo dai

i initially thought this image was an old shield, or a part of a game of some sort. it is actually a small circular map from a 1920's postacard describing the view from an area of the japan alps called subame no koya tembo dai (which roughly translates into english as: swallows hut viewing spot). i love the idea of a rotational graphic you could move around in your hands as you look in all the various directions from one spot...you can see various mountains as well as one symbol for a hot springs.
