Description from the back of the envelope:
RAGGEDY ANDY COSTUME. A clever costume for a masquerade party is this one, consisting of a front-closing blouse, side-closing trousers and a hat. A collar finishes the neck of the blouse. The wide trousers button high on the blouse.
No instructions are given for the floppy bow tie, the mitten hands or yarn hair.
My pattern is a size 14 for a 32" breast measurement. The side length of the trousers in this size is 40," making this a costume for the demographic now known as "tweens." More research is needed into costume parties of this period.
According the Wikipedia article, the first Raggedy Ann book was published in 1918, with a book of Raggedy Andy stories appearing in 1920.
