Penguin Book of Irish Verse,1970,ed.Brendan Kennelly.Cover shows detail from picture "St Patrick's Close" by Walter Osborne in National Gallery of Ireland.Looks like street scene from late 19th century.Walter Frederick Osborne RHA (1859-1903)had, apparently, become Ireland's leading and most fashionable portrait painter at the date of his death in 1903,so the kind of genre painting depicted may have been quite unusual for him.I daresay there is a website for the National Gallery,and I'm sure some kind soul out there will be able to direct you to it.
Good luck!
