The most surprising thing about that photo is how old the balcony that sticks out from the building on the left is - I assumed it was some 70s/80s addition

Thanks for posting those. It shows those of us not old enough to remember the West Pier being open what a wonderful ornate structure it was and also what a great job they did restoring the only remaining structure on the prom.
That'll be the Spurs game when the away fans broke out of the pen. I was only 9 years old and down in the south end of the West terrace but remember my dad getting ready to pick me up and get clear if the Spurs fans had got much closer.
