VTG Hand Carved/Italy Grotto Mary Joseph & Christ Child

This is a pair of Vintage grottos holding hand carved in Italy figures of Mary & Joseph holding the Christ Child. This is from my family given to us by my Grandpa. I have looked all over the internet trying to find these, but with no luck. It is marked hand carved in Italy. These are very unique. They measure 5” tall, sides 1”, base 2.5” x 1.5, 1.75” across front. Will not separate the set
