There have been several series of picture cards devoted to Doctor Who over the years. These include a set of 36 cards given away in 1967 with Walls ‘Sky Ray’ ice lollys.
The cards featured a somewhat long-haired doctor based on Patrick Troughton joining forces with the ‘Sky Ray Space Raiders’ to battle the Daleks.
Judging from the artwork on the cards it seems likely that they might originally have intended to use William Hartnell’s Doctor in the story, and may have redrawn Troughton over some earlier work…
The cards were collected in an album, Dr Who’s Space Adventure Book, which also included games and other features.
