From a 24 May 1995 letter from James Hagenbuch:
The following listing of 121 bottles is the second special offering of bitters’ bottles from the Carlyn Ring collection.
The Carlyn Ring collection contains over 650 examples, and is considered to be the finest and most comprehensive collection of this type ever assembled. Her collecting days started in the early 1950′s, continuing on and off for the next forty years.
