Green cut to clear sherry glasses with square bottom.

Looking for manufacturer’s mark. Name of design. I bought these over 20 years ago from a collector. She remarked that she thought these had been used in New York. That is all I know. I’ve been searching for more to complete the set. I only have five pieces of this size. Any help in identifying these will be greatly appreciated. I live in California. I found these in Apple Valley, California.
