As any proud parent I was delighted to discover that the juice glasses I have been collecting over the years were highlighted in Gene Florance's Collectible Glassware from the 40s, 50s, 60s... to soon realize that they were not juice glasses at all. Instead they are Kraft cheese spread canisters manufactured from the late 1930s to mid 1970s cleverly known as Swanky Swigs. According to Mr. Florance, my collection of Cornflower No. 2 came in two sizes depending on whether they were distributed in USA vs. Canada (not surprisingly I seem to have the USA version). Swanky Swigs came in a variety of colors, sizes and patterns making it easy for housewives across America to use these promotional containers as inexpensive drinking glasses. Huh, who knew?
It didn't take me long during my quick Google search to realize that everyone else was in on the secret but me.
