They used an original picture of the Tamagotchi V4.5. So the one on the picture is real (and I can see a background.. so what do you meen? ) But before you buy it it's better to ask for a picture of the Tamagotchi in his packaging. That way you can judge better if it's a real one
edit: The salesman has been on Ebay since may 2001 and has 100% positive feedback... That seems to me as a good person that does'nt sale fake stuff
That is a real Tamagotchi Connection Version 4.5. That is a yellow mood version, and that was the original packaging online. The packaging in the stores has a UraMametchi.
Of course it's real! It's a Tamagotchi Connection V4.5, in fact I have that exact design. I'm not sure about what you mean by there's no screen, I saw a screen.
