Plenty of additional mail for postal workers to sort and deliver following the penny post promotion.

On 3 January 1984, the Irish Postal Service transferred from the Department of Post and Telegraphs to a new state run company An Post. The launch of the new company marks two hundred years of the postal service. Customers were given a special offer of one penny stamps for hand-addressed letters and cards sent within Ireland and they came out in their droves to take advantage of the cheap postal prices.

At the Central Sorting Office in Sheriff Street Dublin thousands of letters and cards are sorted by staff from An Post.
