(The original design of this map seems to be one of the Century maps [USA].)
Please take a look at the islands in the Sea of Japan - Taka Shima, Matsu Shima, Hornet Is. (Liancourt Rocks) and Oki Is.
Although Taka Shima (Argonaut island) is a phantom island, remaining islands are mapped at the right locations. Most importantly, all these islands were painted in the same colour as Japan.
This is another evidence that western people believed that Liancourt Rocks didn't belong to Korea in the early 1900's when Korean Edict #41 was already promulgated and Japan was yet to incorporate the rocks into Shimane prefecture.
Broughton bay is labeled as Broughton Bay.
