Blythe

Thanks to her peculiarly oversized head and bulging eyes that change colour with the pull of a string, not many girls wanted to play with Blythe when she was introduced by toy company Kenner in 1972.

They were only released for a year and failed terribly as people thought they were a bit freaky and scary.

But Blythe has become strangely popular in recent years and original dolls now sell for between £500 and £2,000, depending on their condition.

Their popularity in recent years was sparked by a book called This is Blythe, in which photographer Gina Garan featured the dolls artfully posed like real fashion models. Others then started picking up second-hand Blythe dolls – which were relatively cheap at the time – dressing them in glamorous outfits and photographing them in exotic locations.

The renewed interest led to new Blythe dolls being produced, known in the community as “Neo Blythes” – and these are pretty valuable too.
