I had been wishing for a nice celestial globe for a while, and this gem finally came to me.
They are much more scarce than their terrestrial cousins, and the nice ones (the really, really, really nice ones, illustrated in color & centuries old) are hugely rare & cost a corresponding amount of pennies. This one is from the early mid-century, so no very old, but very beautiful & within my reach.
You probably won't be surprised by the constellation highlighted in the picture -- it is my favorite -- but they are all equally beautifully illustrated. And I've learned some new ones, too, like Lacerta, (the lizard).
