This is another of the four high-relief plaster reliquaries that I recently purchased. They would look wonderful hung on the walls of an early dollhouse! This example shows St. Benedict, I believe. the plaster relief has been covered with a dome of glass and edged with a brass frame. There is a ring attached to the back of the plaster that can be used to hang it with.
The reliquary measures 2 3/8" long x 1 3/4" wide x 3/4' deep including the dome (6 x 4.3 x 2 cm). This listing is for the one reliquary. The final photo shows all four items together, in case you wish to buy more than one.
