The Wunderkammer des Fundbueros is a compact version of the Fundbuero archive, featuring some of the most interesting objects that were donated. It is currently in storage in preparation for shipping to the US.

Like the cabinets of curiosities on which it is based, the Wunderkammer features a hodge-podge collection of objects. Items are not necessarily identified for the viewer, leaving their origin and use to the imagination. Other objects feature detailed stories submitted by their donor. One drawer also features a small history of Das Fundbuero told through project ephemera.
