Serie 605 is an all-caps geometric sans with some distinguishing features such as the horizontal strokes extending leftwards from the stems in the central bar in A, B, E, F, H, K, P, R and on both sides of the stems of M (M and N follow the lowercase shapes), as well as the diagonal of Z. Typical Art Deco hallmarks are circular C, G, O and Q, which contrast with the other condensed letters, and the rounded apex of A. The missing upper left corners of B, D, P and R seem to conjure up digital pixels and are another particularly felicitous extravagance of Serie 605.
