1900 G. B. 2d registered envelope to London additionally franked with a Transvaal 10/- and three 2/6 each tied by a JOHANNESBURG 18 DEC 00 datestamp. On the reverse is a London 12 JA 01 receiving cancel. Also affixed to the reverse is a table of compensation, showing what it costs to insure the contents of a registered letter. A most interesting item, philatelic but an incredible franking and the only time I have seen a Transvaal 10/- used on a cover!
