J. Ross Portrait Artist and Photographer (see note almost top left) -

Ross 54 Grafton Street, Dublin According to the company’s website, they were established in 1929. A photograph dated to 1930 is captioned: ‘Shadowgraph Portrait by J. Ross, 54 Grafton Street, Dublin’. There had been no photographer at this address in 1929, but ‘J. Ross, photographer’ was listed in 1931. By 1936, Ross Studios were at 3 St. Stephen’s Green. They were still there in 1974, but have since returned to Grafton Street, No 59, as Edmund Ross Studios.

Definitely post-1925 as there was a clothes shop above Noblett's in May 1924 (from advert in the Irish Independent). The hairdressers were (was?) advertising for staff from October 1925 in the same newspaper. The proprietor was Alfonso Palcic, and you can see his name faintly over the window proclaiming "Gentlemens Hair Dressing".

Is that the original image? It looks like it's been run through a sharpen filter.

I don't think it's '30s, btw. There'd have been fewer postwar cars about then.

derangedlemur I think it's 1940s (from skirt lengths and girls' hair dos), and I tweaked shadow/highlight because the shadows were so dark. This'll give you an idea of original...

Men without hats!
