Calling All Architecture Buffs

Once again we've amassed an impressive collection of these architectural models of German Radio/TV towers from the mid-century. Hand lathed and made from a mix of materials, from bronze to copper to stainless steel. This grouping (and I insist they do look best en masse) features a few which incorporate plastic or Lucite elements to replicate the look of windows. A knowledgeable customer once told me that creating these were a prerequisite for graduating architecture school and that some of these models went on to be realized as genuine structures throughout Germany.
They range from 13" to 18"
