Commercial Type has released Schenk, a display family by Hrvoje Živčić based on lowercase lettering that Walter Haettenschweiler drew in the 1950s, seen on a poster for Swiss booksellers. It comes in five weights from Regular to Ultra, without italics, plus a variable version. Alternate capitals with flipped diagonals (A, M, V, W) let letters lock together.
a documented Swiss source and interlocking capitals give Schenk real character; its tight spacing makes clear it is meant for headlines only.
