The nostalgic images show horse-drawn trams making their way up a major shopping street, children paddling on the beach at a famous seaside resort, and the Titanic’s sister ship gliding out to sea for the first time.
They are some of the best photos taken around Northern Ireland between 1900 and 1949.
They range from the devastating aftermath of a Second World War bombing raid in 1942 to fishermen in a pretty coastal village discussing what to do about a glut of herrings in 1935.
Famous races of the era are shown too, including one for which sandbags have been installed outside shops to protect spectators from the cars whizzing round the streets.
What do you think of how Northern Ireland has changed over the last 100 years?

13. Herring glut
Fishermen in the harbour of Ardglass, County Down, Northern Ireland, in August 1935. So great was the glut of herrings that many of them were unable to dispose of their record catches and in several instances they had toiled all night for nothing as the fish had to be dumped into the sea. | Getty Images Photo: Fox Photos/Hulton Archive/Getty Images
