19th-century Russian Icon: Our Lady Of Częstochowa

The Cyrillic inscription on the left identifies the subject as Our Lady of Częstochowa
It is not Polish but Russian and is distinguished by:
The Virgin pointing to the Child
The Western-style crowns on both their heads.
The Child holding a book instead of a scroll.
The icon displays a blend of Byzantine-Russian tradition and Baroque/Western influences (visible in the rendering of the fabrics and the crowns). The style of the face, with soft shading and large eyes, suggests a work associated with 19th-century Russian centers.
There is a stippling technique (small impressed dots) on the golden background and on the garments, a technique very common in the 19th century to simulate the richness of precious metals.
The wood shows signs of aging consistent with the hypothesized period.
The icon bears several signs of wear that attest to its devotional use:
The gold or protective varnish (olifa) has darkened in several areas, altering the original luminosity.
This is an original 19th-century Russian icon.

It measures 36 cm by 30 cm
