Small printed in Italy Religious Art- help identify age and names

I’ve had these 2 little framed prints for several years. (Kind of forgot about them and just dragged then out recently)
The backing of the prints are nailed with tiny nails (hard to see in the photos) i did manage to loosen one of the nails, so that i can look and see if there are any markings on the prints. The Marking says: Printed in Italy not the right lower side; on the left it says SERIE R, No 3
The other says SERIE R No 14
Any help identifying the possible year or names would be greatly appreciated.
