Vintage 1950's Cheerleader Sweater

The perfect Vintage High School or College Cheerleading Sweater. From the 1950's - 1960's. I just saw Bud Anderson on "Father Knows Best" wear one just like this for Homecoming. There has been repairs (see photos). It has the original label but I am not sure that "42" is the size so the measurements are as follows: Shoulder to Shoulder. 17.5" Armpit to Armpit. 20.5"
