NRA blue eagle on this pattern. Who remembers the NRA from American History class? (And no, it's not the National Rifle Association.) Click on the link for a history lesson that's timely today regardless of your political persuasion.
It's one of the oldest I've owned. It's hard to date Simplicity patterns as they have no copyright, but the logo dates it to the early 30s. Unprinted, it shows you how to put the shorts and dress together with dots punched into tissue paper. The amount of labor and care that went into the construction of a child's play outfit shows you a lot about the life of a woman then and now. If you click on the photo of the back of the envelope, you see the complexity of the pattern. No zippers or elastic casings here.
Also take a gander at those fabric suggestions: pique, linen, silk shirting and tub silks. When was the last time you sent one of your little ones out to play in silk?
