I was interested to read your "Decades Past" post. Are you sure about the spacehopper featured in your 1960s illustration? According to the BBC's "I Love 1970s" site and the British Association of Toy Retailers (BATR) site, the hopper was released in Britain in 1971.
Thanks for your e-mail, Mr Thomas.
My information comes from the Cambridge Evening News, 14 November, 1969. The full advertisement, complete with space hopper, is featured above. As the advertisement actually dates from 1969, I would suggest that the BBC and the Toy Retailers Association (TRA - the new name for the British Association of Toy Retailers) are in error on this occasion.
