Pairpoint Garden of Allah Lamp

This is a Pairpoint lamp with a Springfield shade. The base is signed, but the shade is not. The scene is generally called "Garden of Allah", but I have some reservations about the shade. It is of good quality and the shape and size is the Springfield shape, but the painted scene is the reverse of the other "Garden of Allah" scenes that I have seen. I suspect it may be from a contemporary maker, like Bradley & Hubbard. Any ideas?
