McDonalds Happy Meal Amazing World books?

[Crownjewel]

Hi ladies (and gents),

Does anyone know where I can buy these? Or does anyone have any unwanted ones at home that they would be prepared to sell? DSD is trying to collect the full set (she currently has Stars & Planets, and Arctic & Antarctic). We've tried eBay and Amazon but can't find any at all
Thanks in advance! x

Would it be worth contacting McDonald's through their website, and asking them?

Thanks I'll try that!
