Oleg Cassini was a famous designer of men and women's clothing.  Having been a designer to the stars, Grace Kelly, Jackie Kennedy Onassis and others kept him busy throughout his lifetime but he did find time to branch out into other fields and this set of DOF barware is one of his "branch out" fields of design.  Classy gold line designs on clear glass along with his signature and Canadian Club lets us know for whom these were designed.  The last two pictures show the line designs and the Canadian Club label with white paper inside to help these two elements to show up better.  The glasses are clear glass with gold line designs.

The glasses stand 4" tall and have a top opening of 3" in diameter.
