Just won a #725 Town-Plan in an auction. The Cellulose Acetate bricks are in minty condition... The 'Hotel' and 'Esso Service' brick are in good condition. The clear bricks are not yellowed or warped; very pristine. The cars and trees are missing. Only the bottom part of the garage is there... the top part is gone. The box is worn and part of it is flaking off, but the cardboard Town-Plan board is in great shape. I can't believe the set is about 45 years old, but the bricks are in such great shape.
