Absolutely stunning set of 10 antique crystal glass doorknobs.  All have solid brass hardware and original tightening screw.  Round glass knobs measure approx 2" wide.  Most are in outstanding condition with no chips or flaws.  Two knobs have a rough center point-see pics 7-8, which is very hard to see, but feels a bit rough if you touch it.  One looks slightly yellowed-Picture 1, top row, second from left.  A really fantastic large set of matching doorknobs!
