The Thunderbirds Information Sheet
This document provides definitive proof of the official birth order of the Tracy boys. It was mailed directly from Gerry and Sylvia Anderson’s office to fans who wrote in requesting information about International Rescue. The document we have (see below): a picture of it was sent originally to Peter Singleton on April 4, 1966. It was signed by Una, Gerry Anderson’s secretary, on his behalf. Pete Singleton shared it with Stephen La Riviere (TB 1965), who shared it with TICipedia webmistress Jaimi Sorrell on June 10, 2017 (and later publicly as well on the TB 1965 Facebook page).
