An early Superior nightgown pattern by Sears, Roebuck & Co.  Pattern number 8013 - - 9472.  No date but probably dates late teens - early 1920's. It is a size 40 for a 40" bust.

Unmarked with instructions for sewing on the front of envelope and the layout of pattern on the back.  Style is both for a short or long sleeves and applied back yoke.  

In looking at the pattern pieces, I found the wrist band is missing which probably could be duplicated fairly easy. 

Pattern has been used but in decent condition.  Envelope does have its issues as with most of these early envelopes. However, all print is readable and can be followed.
