Between 1949 and 1950 Simplicity produced a line of patterns. They started the same time as Vogue's Paris Originals Line. The patterns have an oversized envelope (8" X 11"). They where nice styles, but they are not VPO's.
Simplicity 8002 c. 1949

Simplicity 8104 c. 1949This one is the closer to a Vogue style. Notice the pleating on the front of the skirt.
Vogue Paris Original Model - 1189 c. 1952 Dessès - Suit - pleats on the side of the skirt. Didn't someone try that on the Project Runway Post Office challenge with BAD results?

Simplicity 8293 c. 1950
After 1950, this line of patterns was discontinued. I have not seen these patterns in the vintage re-issues.
