Most of the booths are gone now, most of them were sold to the public. They were made into showers, couches, shop interiors etc. You can still buy them, for a couple of thousand pounds you will have an original one. Pretty cool investment! If this particular booth would ever go on the market, my guess is it will be very expensive.
The BBC has a very interesting page on these classic icons, with all kinds of information and most of all, where are they now. Follow this link to go to the BBC.
