First in the series of booklets about unusual stamps which are not always accepted by philatelists or are difficult to classify. These include local and fantasy stamps, stamps of phantom states, and stamps of dubious origin of which only little is known. This booklet deals with the history of the island of Trinidad, off the coast of Brazil, and the stamps issued by the self-proclaimed “Prince of Trinidad”. Well illustrated in colour. An excellent study, full of information which would be difficult to find elsewhere.
