These are a very rare collector item now, and the only similar items for sale on e bay are used individual dolls from the same period that are listing for around £20 each with no packaging. You can tell that these are the real deal by looking at the hands of the dolls, with all the modern versions there is no definition between the thumb and the fingers, on these the individual fingers can be seen on the plastic casting.
This is a must for any serious Toy collector, if they are to be given as a toy to children the packaging clearly states not for children under 3years old.
