Looks like the front steps at St. Endas:

Is that lady the mother or the sister? en.wikipedia.org/wiki/Margaret_Pearse en.wikipedia.org/wiki/Margaret_Mary_Pearse

The school opened in 1909. Here are Margaret and Mary Brigid Pearse in Rathfarnham village in 1911. Margarets occupation is given as Matron of College. Patrick and Willie were as gaeilge

This is terrific!

beachcomber australia I'd say it's Margaret Pearse (the younger), who was in her 50s in 1930. Rather than Margaret Mary Pearse (her mother), who would have been in her 70s.

This postcard was produced in many languages, a war propaganda thing?

AI Overview
King George V made several visits to French troops during World War I, including trips to the Somme battlefield and other areas of the Western Front. These visits aimed to boost morale among British and Allied forces, particularly during the intense fighting of the war. He also met with French military leaders and dignitaries, including President Poincaré, Generals Joffre and Foch, and Field Marshal Haig.
Here's a more detailed look at his visits:
The Somme:
In August 1916, King George V visited the Somme battlefield, where the British and French armies were engaged in a costly offensive. He met with his son, the Prince of Wales, who was serving as a staff officer with XIV Corps, and with General Rawlinson, commander of the Fourth Army. He also discussed with Rawlinson concerns about a potential "cabal" plotting to remove Haig and end the Somme offensive.
Other Visits:
In July 1917, King George V and Queen Mary visited the battlefields in France and Belgium, including areas around Calais, Bailleul, Helfaut, and La Panne. They inspected war trophies, watched demonstrations of tanks and aircraft, and met with Belgian royalty and military leaders.
Impact:
These visits were significant for boosting morale among the troops and demonstrating the British monarchy's commitment to the war effort. The King's presence on the front lines, despite the dangers, was a powerful symbol of solidarity.

And here's a picture which appeared in The Graphic on 6th November 1915.

Other newspaper accounts suggest the visit to the front took place on Tuesday 26th October, but are coy about the location. e.g. the visit visited "the village of V, three kilometres from S". The tour of the front took place between 3 pm and 5 pm.
