Fairylite also produced a battery operated viewer for viewing slides.

16 Thunderbirds colour related transparencies with scenes from the TV series.

There is a slightly different version where the black/red colour scheme of the viewer is reversed.

Original price 9/11.

The picture above is of one end of the box illustrating some of the slides contained within.

And here are the actual slides in all their glory. Notice the one of Scott pictured on the box lid does not exist.
