Pre-owned.  From an estate.  It has no easel.  I am thinking there was possibly one attached to the original back that covered the opening.  Glass piece covers the mirror.  Silvering loss to mirror.  Cardboard in the back.  There are some hallmarks on the front but I cannot make them out.  There are also two hallmarks along the oval rim. One looks like a left facing Minerva head w/ helmet. The other looks to be "G7S".  Possibly the work of Gerardus Schoorls.  This piece measures 3 3/8" x 6".  Entire thing weighs 124.2 grams.
