Outstanding signed sash pin by Apollo Studios with highly coveted dragon design.  Nicely detailed and substantial. 

Large purple faceted glass oval measures approximately 32x18mm.  Pin measures 2 1/2" x 2 5/8".

Small issues to note are some minor knicks and scratches to the glass as would be expected for a piece of this age.  Also there looks to be a drop of solder at the base of the bezel.  You can see this in the 2nd photo.  Unclear as to why.  Does not detract.

Please feel free to ask any questions.
