essay Red circular essay "GENERAL POSTAGE/TWO PENCE/Not ex. one ounce/2d." on wove watermarked paper, affixed to reverse of an 'entire' and tied by black handstruck "DUNDEE/SEPT. 30, 39", endorsed with Treasury number "22290/39"; the essay with light diagonal crease but not apparent on the surface and in no way detracting from this excellent example of a very rare essay. Thought to be one of only three known examples. Photo
