Gary Don

For more than 10 years a banner sat stowed away in a cupboard at a little charity shop in Leeds after it was donated. Little did the staff know that one day that same once-forgotten item would sell at auction for a hammer price of £13,600.

Discovered in a pile of objects waiting to be tipped at a routine house clearance, a pair of large ceramic plaques will be offered at Gary Don in Leeds this week.

The entire contents of a West Yorkshire bookshop containing over 30,000 books are to go under the hammer with the bidding opening at just £1.

Gary Don Auctioneers of Leeds was the first subject of Keep It In The Family, a new series of four documentaries that follows a different family business with a succession dilemma each week.
