Manufactured lettering, and not a font, would be my answer.

3D lettering based on Museo Sans, would be my answer. ;)

It looks like Avenir.

Thank you Guys!

I think while both of the other answers do resemble the 3D lettering that was created, they are not identical to it. Museo Sans has a curved l for one thing, and the 'a'top arc is not quite the same. Avenir also has a mismatch with the 'a' bowl shape.

I think the resemblance to either of these is coincidental, and is rather bound to happen because there are so many sans fonts that almost any version of these seven sans letterforms would be likely to look like SOME sans font.
