From David W. Tharp, Executive Director, International Association for Food Protection: I'm not sure when this "tradition" began, but I'm fairly certain that there was an ice sculpture at my first meeting in 1993. From memory, Charlie Felix was the liaison to the Packaged Ice Association (now International Packaged Ice Association). Charlie worked from 1966 to 1985 for the Foodservice and Packaging Institute (per his LinkedIn profile). He became a publisher and consultant after 1985 and was active in IAFP through 2012.
