Further to John Spencer’s comment here…
John kindly sent me some images of another flaw that appears on the Falkland Island Dependencies Map set of stamps.
I reproduce here the comments he sent me. Many thanks John !
Saunders and Harding in their Study Paper No 4 and later Goldberg gives a description for stamps in this position as: Small breaks in top frame line at either end. Defective 2nd E in WEDDELL.
However, the most prominent feature is the spot on the King’s lower right cheek/chin/around his mouth. Possibly it was assumed to be a blemish or a paper fault.
Due to the poor registration between the vignette and the duty plate the spot appears at many different places. The position however, remains constant in relation to the map.
