A mug by Bespoke barware in the UK. They say..."One of five special new mugs in our Cockney Rhyming Slang Range, Tom Thumb is glazed in black with a proper pink face. Tom Thumb measures 15 cm high and 8 cm in diameter and has a capacity of 385 ml (13 fl oz)." Now... the eagle-eyed amongst you might have spotted that this is glazed in blue rather than black with a pink-face and burgundy waistcoat as advertised above. Well, that looked a bit too much like a Toby Jug to me (shudder) so I got hold of one made in bulk for the wholesale bar trade instead. For those not familiar (myself included) with the fine art of Cockney... Tom Thumb = Rum.
