Hold up your left hand, and see if its the same as Freddie Mercury’s. AI might have got past the six-fingered hands, but it is still struggling! 😂

Sub-Collection: Tasmanian and other regions, postmarks with a mining or mineral connection. This piece shows a striking combination of a Tasmania Secretary of Mines departmental handstamp overstruck by a Hobart circular date stamp (CDS) dated 26 June 1902. Although no postage stamp is present, the item is a superb example of official departmental mail from the mining administration. Departmental cachets are far scarcer than regular postal cancellations, and the dual strike makes this an especially attractive artefact.
