geometric sansserif

(x) Sans-serif used in Werkplaats / grotesque smörgåsbord w/ runic S - Otik by Karl Nawrot {Arne S}

Hi,

Ive been looking for this font for some time with no luck. It has some features of Avant Garde Gothic Condensed but some characters are obviously different. Works I found are by Werkplaats students exclusively, so it may actually be an unreleased font... Please help! Thanks
