Very nice indeed. I was obviously slow on the uptake, as it was always around £40 when I used to periodically consider it and then decide to wait for some imaginary day when that seemed affordable. Seems like a bargain now though.
I wanted to get the Silbury monograph when it was published but it was £80, couldn't really justify that.
I don't think it could have sold all that well as there are loads new on Amazon now at around £60 and some 'used'(!) for less.
