Some of the oldest film. It is also 68mm. You know our current films can be 70mm. Most back then were 35mm.
Has footage of Niagara, and since I was just there 2 weekends ago, maybe it is resonating more. Early industrial
innovation came out of Buffalo. Electric power generation was an engine that enabled that.

This is a black and white photo. Has a grid laid over it. Your brain is adding the color you perceive.

Anybody heading to the UK for a vacation any time soon? Remember that Wales is a different country....
Proof positive, if ever it was needed, can be seen here with a sign on the train station platform at Betws-y-Coed...
I bet you ALL noticed the spelling mistake on the last but one line of the Welsh text. Of course it should read '...yn glir i'r gyrrwrr...' - 'in the direction of the driver'.

My comment was in the nature of a jest, a jape, nay, even but a merry quip, Sirrah, and not a serious determination of relative sizes. A simple 'jeux des mots', if I might be so bold as to note.
FWIW, yUK population is ca.65 Million
Oregon population, is, uh, somewhat less.

From your computations it would seem that that is indeed the case.
