Frank,
It looks like a 35mm "dark slide" to me.
How'd I do?

Richard Peck, not Art.

looks like something to unstick typewriter keys when they jammed?

It looks like a pice of packing you put under the corner foot (of a typewriter?) to level it.
Where would I get one of the erasers from?

Piece of plastic is a blocking slide to provide a blank screen for a slide presentation. The square plastic dropped into a slide slot on a carousel slide holder.

I am with Ted on this one

Agree, a dark slide. I used to work for an engineering firm and had hundreds of thousands of slides we used for presentations. Some we used to make on film negatives, mount in the carrier sleeves and color by hand to add color to titles and bullets. Amazing how far we have come.

Who still has a Kodak Carousel?!

All who said it was a 35mm blackout slide were correct.

Denis Griff, Canon Solutions America, Inc, bypassed this system and emailed me first with the correct answer.

I am sending him one of my books that did not sell.

Thanks to all who participated. Glad to know there are more old people out there.
