Actually, not all are 'vintage', but most are, as you can see from the images here. If you haven't worked it out, you can pick up Andy Pandy, Ivor the Engine, Dougal from the The Magic Roundabout, Windy Miller from Camberwick Green, Mr Benn, Great Uncle Bulgaria from The Wombles, Bagpuss, Paddington Bear, Postman Pat, Bob the Builder and more recent attractions Peppa Pig and Shaun the Sheep.
All are of course available as stamps, but there's also a range of gift sets available too. Everything from a framed series through to stamps cards and badges.
All go on sale tomorrow, with the full range available at the Royal Mail website. Your local post office should have the stamps too.
