san serif font

Need help identifying this font

I am trying to identify the attached font image. The font appears to be a san serif font, but has some almost
serif-like characteristics, like the curve to the right of the "u". Note that the bottom of the "g" is curled, but open; and the top of the lowercase characters are chiseled/angled (most obvious e.g. the "i").

Thanks for any help in advance,

I'm currently taking Typography Hierarchy at the Art Institute of Salt Lake City and was turned onto your site through my teacher. He challenged us to find something wonderful and at the same time irritating with type. So I remembered a book, The Bachman Books, to be precise that was very challenging to read because of the font. The book gives no indication of which font is used, but it makes the eyes very tired and distracted when reading. I was hoping maybe you would know which font it is or if it's simply a curling issue.
