This model is also known under the name Supermodel Phone and was manufactured under aptly named Novelty Telephone brand. Not sure if there were ever any other models sold under this brand.
At the time of writing this, in 2019, this model has been around for a decade or so. It comes in various colours. So far I have seen red, purple and pink. There are also versions with various glittering beads instead of a painted surface.
Even though it shape is unusual, technically it is a basic regular digital telephone. It dials DTMF, has a key pad, led and a redial button. The handset cord is hard wired, but the line cord connects with an RJ11 socket.
I found mine for a couple of euros in a junk shop a while ago. My daughter was absolutely smitten by it. What my wife thought about it? You can read about that in this blog. J
