The Munsters (series)
The Munsters is a television series created by Allan Burns and Chris Hayward which was originally broadcast on CBS from 24 September 1964 - 12 May 1966. It was also adapted into comic form within the pages of TV Century 21, becoming a part of its shared universe.
Characters in the series include Grandpa Munster and Herman Munster.
Crossover
Despite being partially published in TV Century 21 - a magazine where all fiction published within shares a universe (including the former The Daleks comic strip), only one work of fiction crosses elements of the The Munsters series over with elements of the Doctor Who universe.
This crossover occurred in the 21 feature 21 Testing..., where readers were asked to answer several questions, with an in-universe framing. One question pertained to relation between Grandpa Munster and Herman Munster (Grandpa being Herman's father-in-law), while the very next question touched upon Unity City, first introduced in The Daleks comic strip.
