6 Deco? Cocktail Glasses

I have called these Deco Glasses because of their shape, but really have no way of telling when they were made.   I found them in a second hand shop and they didn’t know their history.   I just love the stylish look.  They are really well made and have a handmade look to them.    There are no chips or cracks.    Good used vintage condition.  There are 12 facets on each base.   Approx 18cm tall – bases about 6cm wide – 6.5 across the top opening.  Don’t hesitate to ask for any more pictures if you need them.  My laptop crashed last friday so I have a lot of catching up to do with respect to photographs!
