“Senators will agree that we should place no emblem before us in this Assembly that is not of Ireland, in spirit and in workmanship, carrying in it the faith both of the Old Irish world and of the New. I have insisted, therefore, that the form of the casket should go back in direct descent to the ‘shrines’ designed by the Irish over a thousand years ago”

Looks a bit like an owl with beautiful blue eyes.

Mia Cranwill (born Maria Cranwill; 1 March 1880 – 20 October 1972) was an Irish designer and metal artist, and was one of the leading artists of the Irish Celtic Revival.
...
One of her most significant pieces was commissioned by Alice Stopford Green, it was to create a metal casket for a scroll with the signatures of the Free State senators. The casket, known as the Senate Casket, has gold, silver, and enamel on a copper foundation. The shape is based on that of the Gallarus Oratory.[5] Upon its completion in 1924, it received universal praise, being exhibited at the NMI and the Manchester Art Federation. When the Senate was dissolved in 1936, it was presented to the Royal Irish Academy.[4] Newland Smith reviewed the casket, described Cranwill was a "designer and craftswoman who understands the national Irish style and can interpret it, create anew within it, and add to the old and delightful forms a personality and expression quite new" ...

Looks 1950/60s, can anybody ID the car model?

Not sure, but car may be an Austin A30.

75% sure the car is a Morris Oxford Series II (1954–1956) . Rear view ...

I remember, as a child, digging down in the sand in Skerries (perhaps 65 years ago). Obviously not digging far, but hitting a layer of black stuff. My parents told me it was oil. It had a very particular smell. I still remember it. I still wonder what it was. It happened more than once.

The answer, according to A.I.:

The Science Behind the 'Black Oil' Layer

The Lack of Oxygen (Anoxia): On popular beaches like Skerries South Beach or North Strand, the top few inches of sand are constantly turned over by waves and the tide, keeping them well-oxygenated and clean. However, just a short distance below the surface, the tightly packed sand particles block fresh water and oxygen from penetrating.

Decaying Organic Matter: Over time, bits of seaweed, marine organisms, and organic silt get buried under the shifting sand. In an environment devoid of oxygen, normal decomposition cannot happen. Instead, specialized anaerobic bacteria take over to break down this organic material.

The Chemical Reaction: These bacteria "breathe" sulfates (which are abundant in seawater) and exude iron sulfides. It is this iron sulfide that dyes the sand grains a deep, jet-black color and gives it a slick, greasy texture that looks identical to oil.
