Just recently a couple of things have turned up on eBay that are original Ashtead pieces but with later decoration. Although they carry characters from the AA Milne stories, they are not part of the "Christopher Robin" set. The style of the illustrations suggest that they have been modelled on Disney's interpretation of Milne. Disney did not acquire the rights to the books until the early 1960's, so you can work out when these pieces were decorated.

The jug above is an ordinary J12 jug and the plate a standard P11, both in buff (t) glaze.

As "Pooh" and "Christopher Robin" are so collectable it is easy to see why someone may have a go at trying to pass these off as genuine, but buyers should be very wary. They are no more than novelties.
