Religious pictures Mary & Crib scene

I’d like to know more about these pictures please as I don’t know quite what to make of them but I do know I love them!.
Beautiful artwork that looks printed as I can see dots but some areas of gold look to be applied differently (no dots) like the halos.
Also what is it likely printed on?. Through the glass the blue appears to have no grain like paper and there is no division between blue and white. Wondering if on metal as one has cracked glass and there looks to be bare metal.
c12.5cm tall and 10cm wide with some sort of fibre board back and sealed brass frame.
Any information as to age or construction would be really appreciated.
Thankyou

 

More gold dots and the damage.

 

They are lovely, K. You're right, the gold looks added later, so an embellished print or whatever the correct term is.
Mary is depicted as Queen of Heaven or Our Lady of the Angels, the crib scene is usually called a nativity scene.

The city of Los Angeles is called after a similar Madonna, but one with a baby Jesus in her arms, and no moon crescent.

 

It’s bugging me how it is constructed. The blue looks like enamel of sorts, presumably the picture is printed, can you print onto metal? Hmm, annoyingly I can’t take it apart as it’s a sealed unit although the broken one may yield some secrets at some point!.

Hence the starry halo

 

And the crescent moon under her feet.

It is a way of incorporating ancient Goddesses like Ishtar/Astarte into Christianity.

 

I would have said the Mary is a version of the Immaculate Conception. See Guido Reni, Murillo Paintings Google shows me for 'Mary Queen of Heaven' are quite different.

 

She is really stunning.
Thankyou for the link

 

The image looks like a chromolithograph. In the second half of the 19th century, methods of transfer and offset lithography were developed that allowed colored images to be printed on metal, and were widely used for packaging and advertising tins.

"With the wide spread use of chromolithography the importance of packaging and labels increased. Lithographic printing of tin cans was presenting unnecessary technical difficulties. Non-porous metals simply didn’t absorb the ink. Sheet metal and stone printing surfaces also offered a can full of flexibility challenges. By 1850 transfer-printing methods were being invented. During these processes a reversed image was printed onto thin paper and then transferred onto sheet metal under great pressure. The paper was then soaked off which left the printed images on the tin plate.
Robert Barclay, an Englishman, invented offset lithographic printing on tin in 1875. His process started off with an image drawn on a stone and then inked. A nonabsorbent cardboard impression cylinder then picked up this image. From there it’s immediately transferred to a sheet of metal.On a later stage Barclay started using a rubber-coated cylinder to fix the image to the metal."
