Every three years, the small school I attended hosts a full-school reunion. I've missed the last three gatherings, and this summer was no different. My class (1969) was small - five boys and five girls. Over half of us still live in the area, but our paths don't cross much.
I wore this sweater a lot for three and a half years, and earned the letter and the chevrons for Pep Club. Boy's school sweaters were made with four white stripes on the right arm to indicate the number of years the boy lettered in a sport. The stripes were covered with a removable red covering. Boys were also issued pins to place on their varsity letter - basketballs, footballs, racing feet, etc. Some schools also awarded varsity letters for band, but seldom for choir.
Pep Club was a big deal in my high school years because it was before Title IX had been implemented. The Pep Club wore wool uniforms, and we were issued demerits for sloppy or dirty uniforms or sneakers, chewing gum, and talking and not cheering during games. Does anyone else remember polishing their white canvas sneakers and wearing them wet?
Our Pep Club also performed flashlight drills during half-time of several home games. We created formations as we marched, visualize a marching band with flashlights instead of instruments. I know it sounds lame today, but in those days it was impressive.
Letter sweaters have lost their appeal with today's high school students, but schools still award varsity letters and pins for boys and girls sports, music, speech, and theater. Some boys order the traditional letterman coat with leather sleeves.
