Just in case you are having trouble locating Demerara, it is the old name for the capital of what was once British Guiana. The city is now Georgetown, Guyana, South America.

Eccentric millionaire John DuPont, now serving time for murder in Pennsylvania, used to use the pseudonym Rae Mader. It's an anagram for Demerara. Why? Because he owned (and apparently still owns) the only known example of the famed British Guiana 1-cent magenta postage stamp of 1856. That stamp bears a Demerara cancellation.
