Reverse painting on glass about (2ftx3ft) painting is of the Salt Lake City Mormon tabernacle. There is an inlay of mother of pearl making up about 30% of the painting. The condition of the painting is flawless. The building itself may be a transferred image of the church as the details are flawless and you can even make out the prayer in one stained glass window.
The frame is in good condition but probably not original, it had a paper backing at one point but no longer does.
If you remove the frame backing you can see the foil Laid over the painting. The foil is not adhered to the glass and you can lift it lightly to reveal the individual pieces of mother of pearl.
There are no marking, signatures, dates that I can find except a faint stamp on the cardboard used for backing. It has something hard to make out and then New York, it may just be a company stamp from a random box used as a backing.
It was given to me by my mother in law who go it from her mom. We know nothing else about it but it probably came from an auction in Montana.
