Minature Bottles produced for advertising and promotion. All of them are from the late 1950s and 1960s
From left to right. 1.PLJ (Pure Lemon Juice; 2. Adam's Old Monk Port; 3. Stout especially brewed to promote Wiebull's Barley Seed: 4. Guinness; 5. Harp Lager; 6 Pol Roger Champagne; 7 Pimm's No 4 (that's the Rum based one).
All would have contained the drink advertised on the label except the Pol Roger which has a label on the back which (rather queasily I think) proclaims that it contains sugar syrup. (Did anyone ever say 1953 was a vintage year for sugar syrup. I think not)
The pound coin should allow you to gain some idea of the size of the bottles.
If you live outside the United Kingdom you should know that the pound coin is our largest coin with a diameter of One Metre (aprox 3 feet). This last statement is a lie.
