The envelope description states:
LADIES' AND MISSES' SMOCK, in Two Lengths; Back Shoulder Edges Extending Over Front; One-Piece Full Length Sleeves Perforated for Shorter Length.
This is a nice smock. The shawl collar and belt add a stylish touch, and you can stash your knitting in the big patch pocket.
The quality of the pattern envelopes for Ladies Home Journal patterns at this period is uniformly dreadful though the pattern tissue is fine. This unprinted pattern appears to have been used. No separate instruction sheet was included.
There was an extensive campaign to knit for the soldiers during World War I, so the illustration would have resonated with women.
March 2, 2013 - updated and added scans of pattern envelope.
