This vintage pattern is complete, factory-cut and still in factory folds. Pattern pieces are in excellent condition. Original mailing envelope is in poor condition. Instructions are getting fragile at the crease - I recommend making a copy to work from in order to preserve the original.
From the markings on the envelope, we can date this pattern to sometime between February 25 1949 to December 21, 1954. To learn more about vintage mail order patterns, see http://wesewretro.com/2011/11/how-to-date-vintage-mail-order-sewing-patterns/
