Yup, that was it.
Rather than having one figure that we sent around the world to each other, with the difficult and expense involved and the risk of losing the figure, we thought it might be fun to select an cheap and easily acquired DS set that anyone interested could buy, and include them in some travel pictures.
Sadly it seems the set is no longer available, so there are a limited number of Maisie and Freds around.
Why an old couple? Old couples are inherently funny.
