The only difference I see between these two is that the one in the auction has the protective film over it. Did yours not come with this film over it? If so, that would be reason enough to get a return in my eyes, as you would not be able to apply it properly. Otherwise, they look identical and the description doesn't seem to be misleading.
Not trying to pick sides here, but a decal will never look that great on an apron, regardless of whether or not it is cheap paper, silk-screened vinyl sticker or some sort of transparent variety. I'd consider it a better than nothing sort of solution, but it would still be susceptible to damage and scratching.
This design is simple enough and is only two color. You could frisket off your apron and spray it yourself, and use this sticker as a template for the cuts. Then you can clear over it when you're done. Use waterslide decals for the type. I enjoy doing that sorta thing though, have done it to most the aprons on my games. Doesn't take too much time to do. Basic Williams SYS11 game apron can be frisketed out for each color, airbrushed (or spray-painted), and cleared in about 3 hrs or less, sans drying time.
