UPDATE: There are two of these rare early Pee Chees on eBay.
“Vintage, these have wear consistant with use and age. Small tears at the bottom edges where the inner pockets start, subject names written in pencil at the top edges. Overall, good condition for their age.”

I have one of these bought at a local garage sale. Really nice condition. I’m into collecting aviation stuff so I display it Airplane showing. May have to find a place I have enough room to display it opened and showing both front and back.
