Simplicity 3259 vintage sewing pattern circa 1950s tunic skirt size 11 bust 31 1/2

This is a vintage sewing pattern from Simplicity, number 3259. This probably dates to the late 1950s but I could not find a copyright date. This pattern is partially cut but all pieces are present and in good condition. The envelop on this is heavily stained or yellowed on the front and torn along one side. The pattern is size Junior 11, bust 31 1/2, waist 24 1/2. The envelop description is: tunic has convertible collar, yoke, set-in sleeves, front button closing, and openings at lower edge of side seams. Top-stitching details tunics. Skirt has side zipper closing and back vent. V 1 and 2 features long tunic, set-in sleeves, French cuffs and a pocket. V 2 and 3 tunic is in contrast to skirt. V 3 short tunic has roll up sleeves.
