The piggy banks come traditional with flower decoration. Therefore it's easy to recognize this piggy banks as a Dendan, and also by the shape with the eye-catching nose. I already had 4 in my collection and I thought that it was enough. Until I bought this one in Hoek van Holland (Car boot sale). For this piggy probably is a whole new mould used, because the stamp is sharp and the pig as such has certainly 10% shrunk in terms of volume.
From Dendan Ware as a brand or as a factory I can't tell you anything else, no info found until today.
