You Just Can't Put An Age On Them

Could you put a date on these designs? It's amazing that some designs look as though they have just been thought of. Others you see all the time but never think about just when they first appeared. Take these examples:
The Lady Chair (which I couldn't resist including) was designed by Allen Jones way back in 1969.
The Lava Lamp (I used to own an original that I bought when they first hit the market) was designed by Edward Craven Walker as far back as 1963.
The Waste Bin which we all are familiar with was designed by Gino Columbini in 1965 and is still in production.
And that Spotty Fold Up Chair was designed by Peter Murdoch back in 1963. Amazing.
