This set of 4 wine glasses are hand made by an unsigned artist.  No two of these glasses are alike.  They are speckled and swirled, which adds an unique touch to these pieces.  The bottoms feel rough from where the artist detached the pontil.  One of the glasses wobble a little on a flat surface.  This is how we know they are a one-of-a-kind set.  They are beautiful and date back to the early sixties.  I acquired from an estate sale in which I was told they've had them since that time.
