A grey brick from the Dolphin's Barn birckworks.

The Dolphin’s Barn Brick and Tile Company was established in 1900, and bricks with the Dolphin’s Barn stamp were used widely throughout the city between 1900 and 1942. The distinctive yellowish colour of the bricks means there is a tendency to describe all bricks of a similar colour as ‘Dolphin’s Barn’ bricks, even ones that were produced long before the factory opened. The company was a major employer, and its bricks were used in many notable buildings around Dublin, including the GMB in Trinity College, Steevens’ Hospital and the National Gallery of Ireland. The company merged with the Mount Argus works and the Rathnew Brick Company in 1921. It ceased operation in 1942.

Prescott's six hour service for safe, speedy, super cleaning' Colour poster showing an Aer Lingus plane flying over Dublin airport and green fields.

This poster has nothing to do with air travel. It is an ad for Prescott’s dry cleaners in Drumcondra, near the airport. The pitch borrows the glamour and speed of commercial air travel to make a mundane service seem more exciting. The plane in the picture – a Fokker Friendship – puts thead some time between 1958 and 1966, when the Friendships were phased out of service. A miniature incarnation of Dublin airport is depicted at the bottom of the ad. The airport was designed by Desmond Fitzgerald, who was only 26 years old when he secured the commission.

Mahogany-cased signalling instrument for use with the Central Telegraph Office (CTO), GPO-College Green street pneumatic tube.

This is the block signalling instrument from the GPO end of the CTO-College Green Branch Office pneumatic tube, used for sending telegram forms between the offices.

Since only a single tube was provided, it was necessary to let the far end know if the tube was occupied. The instruments were also connected by a wire and the clerk would check that the indicator was showing "Tube Clear" before inserting a carrier and a switch was pressed to ring the bell at the far end and change the indicator to "Carrier in Tube" to let staff know that a carrier was on its way.

This tube (originally one of three "street" tubes) was reinstated in November 1929 at the public counter and with the reopening of the CTO in early 1932, was extended there. The tube lasted until the closure of College Green Branch Office in 1952, when St Andrew's Street Branch Office opened.
