Apologies for the glare of the flash.  I had a heck of a time photographing this stem.  There are lots of etches with vases in them, but I haven’t been able to find this one.  I have two of these sherberts (?).  They have a very wide optic.  When you look into the bowl you can see that the rim has a panelled look.  Don’t know if this makes sense.  I tend to view this etch as ‘masculine’, not as pretty as others.  It is interesting and I am keen to determine its provenance.  Can’t recall where I found these glasses.
