You actually won an m101-5 F&B Hartzell. The reason I differentiate is because m101-4 F&Bs, at least numbers 1-20, are slightly larger (usually just wider), so if you only have those to compare that could be why.
F&Bs as well as other m101-4/5s can vary noticeably in size. What are the measurements on yours? If this is the card you won then I believe it's good; in fact, it does not look narrow at all and at most a touch short.
For contrast, here's an m101-4 F&B fatty and then a somewhat skinny/short m101-5-- each is outside the "norm":
