That's the Futura. Bold or Heavy, I think. This is quite a well-known (and expensive) font. If you don't have it available maybe you can get a look-alike for a much lower price. Almost all well-known fonts have a number of fonts that were made by other people and look 99% the same but cost less. Maybe on one of those "500 fonts on one CD"-packages you can find something. If you don't need it for a professional purpose that will probably do as well.
