by Godden:
A rare version of Her Majesty Queen Alexandra [see go20 on this site] is found mounted on the same card as King Edward VII [see go108 on this site], and some later silks, from 1905 on, are found on a darker card-mount without a title.
Other comments:
There is a second title, with the same pair of silks mounted on a single card, but with the slightly different title of "Their Majesties King Edward VII and Queen Alexandra" [recorded as go4 on this site].
Godden does not record this alternative title however.
On Godden's version above, Edward is on the left, and Alexandra on the right, whilst on the alternative go4 version, their positions are reversed, so that they appear to be looking towards each other.
