What looked like a sort of rival Moon Maid in what must have been the same general period appeared in an advertising campaign for a line of men's clothing
.
In the ad itself, she is called both "The Hardwick Maid"
And a "Moon-Maid".
Previous Hardwick ads had used the term "Hardwick Knight" ( otherwise without much of an indication of knighthood* ), and "Hardwick Maid".
So the "Moon Maid" angle was a variation of their exsisting ad campaign.
*And I think the idea was that the "Knight" was supposed to be like the character of John Steed on the television program THE AVENGERS.
