Avant-Garde Bauhaus by Herbert Bayer

As one of the more recognized designers from the Bauhaus Institution, Herbert Bayer was a teacher, art director, and architect originally from Austria who contributed a great deal of influence to the Bauhaus movement during 1919-1933.  His work represents the essence of Bauhaus design in its geometrical minimalism and style.  Really love the elemental simplicity and shape-shifting going on in these pieces here, very pleasing to the eye.

He's also made some nice fonts as well, with Universal being my favorite from him.

Grandiose Geometrics from Anton Stankowski

Anton Stankowski was a German graphic designer, photographer, and classically trained painter best known for his Deutsche Bank logo.  His design style utilizes minimal geometry in a really cool way through his use of grid-based formatting and bold colors.  He doesn't use type a whole lot, but when he does the placement and sizing are pleasantly attractive.
