The examples below are all PP58 a 1d. lake-red (SG 43 or G1) with a Wm. Dawbarn & Co., Liverpool type 19 overprint, reading downwards on cover.
As you may have noticed, all these covers were addressed to the same recipient one Arthur Wyatt Esq. of Bangor, North Wales. This may lead you to suppose that all the covers were purchased by me as a job lot. In fact they have all be purchased singly over a period of more than ten years.
