1966 Topps Lost in Space trading cards are one of the most popular sets from the era. Charting the early voyages of the Robinsons and their fantastic trip into space, the cards include images from the first handful of the show's episodes.
The 55 card set features a black and white image from the show's first season on the front. The backs include a detailed illustration, the card number and a short writeup that describes the front photo. The story on the back of the card sometimes varies from the storyline from the episodes the image on the front of the card was taken from.
Unauthorized reprints of this set have surfaced.
