Offering £20 (e12,000) the reward notice stated: ‘On Tuesday morning, 14th of June, whilst Felix McGennis, one of the letter carriers of the General Post Office, was delivering his letters on the North Wall, he was violently assaulted by three men, at present unknown.

‘Notice is hereby given that whoever will apprehend or convict, or cause to be apprehended or convicted, any of said persons who assaulted the letter carrier aforesaid, will be entitled to a £20 reward.’
Another notice, from February 20, 1824, offered a reward of £100 (e60,000) for the return of 15 £100 banknotes that had been stolen in the post.
The banknotes had been posted from England and had been destined for Captain Thomas Fenton at Bilton’s Hotel on Sackville Street (now O’Connell Street).
Mairead White, manager of the National Print Museum, told Northside People the posters should create a lot of interest amongst the public.
“With so much of the Post Office’s administrative record destroyed during the troubles of the last century, these notices are a rare survivor of the pre-1916 General Post Office,” Ms White said.
“These Reward notices offer an insight not only into the functioning of the 19th century Irish Post Office, but also into aspects of local history throughout the country.
“Their style and format covers the transformation of the Post Office from what was fundamentally an 18th century office to a great Victorian institution whose administrative importance was unrivalled.”
Ms White said the National Print Museum was delighted to be taking on the exhibition.
“After Stephen Ferguson found these posters, An Post had decided they wanted to exhibit them but they didn’t have the proper space to do so at the GPO,” she explained.
“Given that the notices are old prints, it made sense that we exhibit them at the print museum and I am sure their importance as an original historical source will be appreciated.”
The National Print Museum, Garrison Chapel, Beggars Bush, Haddington Road, Dublin 4, is open seven days a week, Monday to Friday, from 9am to 5pm, and Saturday and Sunday, 2pm to 5pm. Admission to the exhibition is free.
