Federal produced the Rhythm pattern in 1959 in a crystal salad set. The Limelight (avocado green) color shown here was produced toward the end of Federal's production in the 1970s and was advertised as a chip 'n dip set. This color often indicates production during this time period.
According to Craig Schenning, after Federal's closure, Indiana Glass purchased the molds for this and a smaller bowl. It was sold as a salad set and a chip n dip set and was also called Rhythm. A 1982 Indiana Glass catalog only shows it in crystal, but he seemed to recall seeing it in black glass as well.
