Walls' Sky Ray lollies advertisement
Walls' Sky Ray lollies advertisement was a marketing campaign featuring Gerry Grant as the Second Doctor. It was released in 1967 in conjunction with Dr Who's Space Adventure Book. Two different versions are known to exist, one in black-and-white (meant for television) and one in colour (meant for cinemas). Each version used different takes, and different actors in some cases.
The ad began with a unique live-action scene of the Second Doctor (notably not played by Patrick Troughton) attempting to pilot the TARDIS, when he is attacked by two Daleks who have entered the ship. The black-and-white version gave a wider context of the Daleks entering the TARDIS control room, while the colour version starts with the Daleks already in the room. In both versions, the Doctor covers his face out of fear of the Daleks (and also in an attempt to hide from the audience that the actor is not Troughton). As promoted by the advertisement, the price of a Sky Ray was sixpence.
Not heavily connected to the actual short story featured within the campaign, Daleks Invade Zaos, the short trailer is notable for being one of the few colour depictions of the Second Doctor's era on-screen during the 1960s. While the TARDIS set was created especially for the trailer, the Daleks were real props which had been used on the show, meaning that viewers can use the piece as a window into what those props would have looked like in colour. The advertisement is also useful to historians who wish to understand the product itself, as the frozen treats would have been less likely to survive than similar tie-ins. Its feature role outside of the live-action segment is in illustrating that the ice lollies resemble the space-ships within the featured short story. It has become a novelty to many fans since its release, and was featured in More than 30 Years in the TARDIS.
The scene is also one of very few stories to feature the Doctor's pipe hat, which was gradually phased out within the Second Doctor era.
