I have a large collection of The National Sporting Magazine from around 1950 in excellent condition. They cover cricket and football teams. I am interested in finding out if they have any value but I have no idea how to go about this. Any help greatly appreciated! Thank you

Theres a place in the strand in London specialises in that type of thing...
