Up to the 1960s, pubs got deliveries of Guinness bottles that were empty and without labels. The bottles had to be filled and crown-tapped; the labels had to be pasted on by bar staff.
These two images show such labels which have the name and address of John Mulligan’s on them. This was usual for all other pubs which also put their own distinct name and address on the labels.
The time-consuming and exacting work of bottling and labelling gave way to more factory-driven operations in the 1960s.
