Etch is shown on Glades Mayonnaise. The Cosmos band etching has also been found on a Cambridge #135-10 cracker plate.All other examples were on either Paden City Glades or Partyline pieces plus some of the Paden City Vases.
The etching is a simple flower and leaf border but if you look carefully, you can see that the background is the same as the one found on Paden City's Garden Magic etching. See "Paden City Glass Company" by Walker, Bratkovich and Walker.
