The Perkins Bacon Archive Facsimile is a two-volume set just published by the Royal Philatelic Society London.
The Perkins Bacon Archive held by the RPSL is available to researchers for consultation by appointment, but that requires a trip to London. In order to make this primary resource more accessible, the RPSL is making high resolution images available on its website. These books are a reproduction of the General Account of Postage Labels 1840 and Postage Stamp Warrants 1840-1845, and are intended to be part of a longer series with additional titles forthcoming.

Perkins Bacon Archive No. 2: Postage Stamp Warrants 1840-1845
