1d stamp duty 1st Sideface on covers

Here are 1st sideface covers with 1d stamp duty stamps. They were valid for postal use from 1880 until 1 July 1892. Despite these stamps being valid for postal use, most extant covers give definite signs of philatelic use. It can be difficult sometimes to discern if the covers were genuinely postal or philatelic in origin. For other 1st Sideface covers see here

1892

1st Sideface 1d revenue stamp x 1 (standard town rate) from Brisbane GPO to a Brisbane GPO box dated 22 April 1892. As this stamp was not issued after 1 January 1880 it is almost certainly a philatelic cover. Seen in a private collection

Posted at Woolloongabba, Brisbane on 23 April 1892 to Fred Hagen in Sydney. Barred numeral cancellation no 472. Fred Hagen at the time was president of the Sydney Philatelic Club. Given this and the late date, this is a philatelic cover. Ex Butler
