St John Ambulance
The logo of the St John Ambulance appeared on some police boxes.
The Doctor's TARDIS
The logo appeared variably on the First Doctor's TARDIS. It was either non-existent, (TV: Twice Upon a Time et al.) very faint, (TV: The Aztecs, The Ark etc.) or in perfect condition. (TV: The Space Museum, The Chase et al.)
It was not present on the Second Doctor's TARDIS for the most part (TV: The Power of the Daleks - The War Games) but was still seen occasionally such as during his travels with John and Gillian (COMIC: Master of Spiders, Egyptian Escapade) and during some of his travels with Jamie McCrimmon and Victoria Waterfield. (TV: The Tomb of the Cybermen, The Web of Fear)
It returned on the Third Doctor's TARDIS very briefly as he arrived on Earth (TV: Spearhead from Space) but afterwards disappeared again (TV: Spearhead from Space et al.) before appearing very briefly during a travel in space. (TV: The Claws of Axos)
It then seemingly disappeared finally for multiple incarnations (TV: The Claws of Axos - The Eleventh Hour) until it re-appeared on the Eleventh Doctor's TARDIS and remained on the Twelfth Doctor's TARDIS. (TV: The Eleventh Hour - Twice Upon a Time)
The sticker was mostly absent from the Thirteenth Doctor's TARDIS, (TV: The Ghost Monument, et al.) though it made an appearance once. (PROSE: Black Powder)
