from Caithness Glass by Mark Hill
<<Design CT 117 from the Shakespeare series designed 1989 by Colin Terris. A popular wedding gift, produced for decades. Later examples produced with a screen printed stencil so lacked the depth and detail of earlier pieces.>>
so its age could be anything from 20 to just a few years. depends on quality of the sandblasted design I guess.
I bought one recently which was very disappointing - obviously the one I got was a later version although it has the 90's- 2000 pink & clear label.
