This superb work explores the history and sociological background to Elihu Burrit’s campaign for an Ocean Penny Postage; the narrative extending to the Beechings Imperial Penny Post envelope of 1899. All the various types and states of Ocean Penny Postage illustrated envelopes are described and illustrated, many in colour. The book includes a database of known envelopes; and an indication of relative rarity, with recent auction realisations. Profusely illustrated, much in colour. A major study.
