Info & Quote: I don't know what it's worth - Star Wars teaching kit

So my dad has owned this Star Wars teaching kit since the early 90’s.

Everyone he has ever talked to who is into Star Wars has no clue about it, and has never heard of it. Trying to do my own research I discovered a similar one was on Ebay a few years back, but the ad is so old that I can’t see any info on it.

It’s a boxed set which says: Star Wars George Lucas Pendulum Press Contemporary motivators.

Inside of the box there are a total of 4 items. 2 books, a cassette tape, and a film strip.

The first book is “The Illustrated Format” an effective teaching tool.

The second book is  “Star Wars” It has a copyright of 1977, and it’s a small comic book in black and white.

The cassette tape has a copyright of 1978, and it’s the sound that goes along with the film strip.

The film strip itself, I have not personally taken out of it’s little canister, but when I open the canister it looks like it is in perfect condition.

Any ideas of value? Thanks!

I really don't have a clue what is on the filmstrip. I am guessing my dad probably played it once (He use to have the proper equipment) but I have never watched it. This little box set was just a throw away item at the school he worked at.
