Anyone know which episode is used for the TRU VUE slides (not the VIEW MASTER slides)?

Any Tru-vue set of a TV series that also was released as a View-master used the same episodes and photos. The difference was that you saw more of the photo along the bottom with the story text super-imposed on the picture.

what's TRU-VUE?

Stereo photos like the View-master, but instead of a round card,
it was a long card that used a different kind of viewer.
