Bought at auction!

I was at an auction in London about 10 years ago and one lot was a box of paperwork, postcards, letters, things cut out of a newspapers, just a box of odds and ends. I had no intention of buying the box (and had not even looked in it). Unfortunately for the auctioneer, nobody wanted this lot and he looked at me because I tended to buy 'cheap' things that wouldnt sell. So I accepted the suggestion that I buy the box for £1 and I took it home along with a car full of other purchases. A couple of months later I picked up the box at home to have a look at its contents, I lived at the time in Basingstoke, Hampshire. I came across a picture postcard that looked familiar. It was a picture of the house that I was brought up in, in Plymouth, Devon! The picture was taken in the 1940s. Where I lived there had been a post office opposite. I guess the picture postcard manufacturer would have stood outside the post office and taken a picture of my house representing the area. The postcard is now a prize possession! Why was I at the auction at the time? Why was this box of 'rubbish' at the auction at the time? Why did nobody else want to buy it? What made me buy it? All a coincidence at the time I guess. I get a tingle down my back everytime I relate this story! Geoff Gill
