What I hear you saying is...

From Wikipedia:

The yellow Pee Chee Folder was a very common American school item in the second half of the 20th century. It was first released in 1943 by the Western Tablet and Stationery Company of Kalamazoo, Michigan. Pee Chees were later produced by the Mead Corporation. They are not currently being produced.

These relatively inexpenisive folders were made of card stock and had two internal pockets for the storage of loose leaf paper. The pockets were printed with a variety of reference information including factors for converting between English and metric measurement units, and a multiplication table. The folders had fallen out of general use by the 2000s.

The illustrations on Pee Chee folders changed occasionally over the years, but usually depicted high school age students engaged in sports or other activities.

"Other activities". Gotta luv that. Every year we'd get new Pee-Chees, and by the end of the first week, we'd doodled and caricatured the highest-level of grade-school wit we could muster -- embellishing the retro-photo line-art with props, and adding thought bubbles to each character:

The guys in track suits were always running from a class pariah or evil teacher. The football players were usually expressing discomfort over some type of... er, "compromising" positions. The smiling tennis player usually frying up bacon and eggs in her racquet.

Pee-chees were the pallete of grade-school america.

But as I learned the other day, several folks from the south and east coast seem never to have heard of these. If you're one of these unfortunate souls, all is not lost. Apparently there's a mint-condition Pee-Chee for sale on eBay right now -- current bid is a paltry $21.50.

If you've never spent an afternoon drawing on a Pee-Chee, well then it's time to get 'cher doodle on.
