Below are some old Dublin advertisements which were taken out in the Capuchin Annual of 1934. The annuals are a great source for these kind of old snapshots of Dublin life, and these are some of the ads which stood out after a quick glance through the publication.
Firstly, this ad for the Magalen Asylum on Lower Gloucester Street caught my eye. “It shelters one hundred and twenty-five Penitents who pray several times daily for their Benefactors, living and dead.” Chilling.
'The Magdalen Asylum'
This full colour page from the Dublin Illustrating Company on Townsend Street is beautiful, speaking of the “hurrying age of machine production” and the skills of the craftsman which were then in risk.
'Dublin Illustration Co'
You won’t see anything like this one from Specsavers today…..
A great opticians advertisement.
Lastly, this ad from Elvery’s seemed worth scanning up too. A long way from the rugby jerseys of today.
Elvery's Clerical Coats!

I have a funny feeling the dublin illustrating company still has its sign up on a building. Somewhere around townsend street or pearse street
Theres a great Elverys catalogue in the nli from 1934 as a matter of fact. The names on the soccer boots are gas. Well worth looking up!
Slightly different subject matter (and maybe covered here in another post), but the topic of advertising and the era you are referring to reminded me of the old advertising board for Cadbury in Pearse Station.
