In 1966 Monty Gum (a Dutch company) produced a set of cards titled TV Shows. Of the 55 cards in the set, numbers 17 to 29 had a Thunderbirds topic.
The anonymous, plain white backed cards were sold in packets with chewing gum. Today the cards are very rare and when they do turn up for sale can reach up to £10 each in a good condition.
