These labels were provided by the Vogue pattern company to home sewers who bought Vogue patterns. The Paris Originals and Couturier labels came out in the 1950s and the Vogue Americana patterns and labels date to 1967.
If you find one of these labels in a garment, it is an indication that it was sewn using a Vogue pattern. Often, these garments are very well made, as some of the patterns were quite difficult to sew and were attempted only by skilled seamstresses. With a little research, one can often identify the original designer.
