This is Simplicity Printed Pattern 2562 from the 1940's. This pattern includes 17 pieces so that you can make a jacket, hat and overalls. This is a unisexed pattern.
It's for baby or toddler size 1, which is breast size 20 inches, waist size 19 1/2 inches and hip size 21 inches.
There are 17 pattern pieces which have all been cut out and have been accounted for. This includes the piece with the Monkey transfer and the trial motif. The envelope is in poor vintage condition, the graphics are somewhat still good, however the envelope has serious signs of wear and tear. The paper instruction sheet is yellowed from age and while still very readable, should be handled with care as it is starting to look fragile. The tissue paper pattern pieces are in good vintage condition and appear to have been gently used. There are still some straight pins holding pieces together.
