is there a catalogue/catalogues which list international revenues?
Hi BobbyT there are loads of Revenue Stamp catalogues that I see mentioned, but as far as I can see they are specific to one country I've not come across anything like the Scott or SG catalogues for the whole world for postage stamps.
The name Barefoot often crops up, John Barefoot publishes a number of catalogues for various countries. I think they're in quite small runs so second hand may be the best route
Putting a search like "revenue stamp catalogue" into the Bookfinder website or one of the other bookseller sites may produce some results
