Well pending Grandarog's confirmation the background looks identical. Why has the RBL got them though?
The Lion represents the Lion of Judah. King David was of the tribe of Judah, and so Jesus of Nazareth was "of the line of David", and hence of the tribe of Judah. Revelation links the Lion of Judah to Jesus. The serpent is of course the tempter from the Garden of Eden in Genesis. Hence the serpent came to represent Satan. The symbolism is therefore of the second coming of Jesus vanquishing the Devil at the end of time. The other statue of the Lioness protecting her cubs is also full of Christian symbolism. The lioness is the bride of the Lion, Jesus, and represents the Church. The Church is therefore protecting her "cubs", us, from the serpent/Satan. Now you see why I assumed an ecclesiastical setting!
