A vintage 1940s novelty "school" sweater by Jantzen. This sweater is a cardigan that buttons up the front. The blue knit fabric feels like wool.
Size: approximately size small to s/m, but has some flexibility because of being a knit
Bust (unstretched to stretched): 36-40"
Waist (unstretched to stretched): 30-36"
Sleeve length (from shoulder to hem, with sleeve uncuffed): 20"
Condition: Very good. Very subtle color variation (I didn't notice it until I unbuttoned the sweater). Most noticeable when sweater is unbuttoned and you're looking at the button placket that is covered when the sweater is buttoned up (see last two pics).
