The Goerz Westentaschen Tenax, also marketed as the Vest Pocket Camera, is a small folding camera designed for portability. It is an early-20th-century German plate camera intended to slip into a waistcoat pocket, positioning it as a compact travel option when new.

Sales data is very limited: a single recorded UK auction hammer result from April 2025 sold for £44, which sets the only current reference point for what a Goerz Westentaschen Tenax sells for at saleroom level today. With just one data point, the price you see for any individual example will swing widely with cosmetic condition, completeness of the leather case, and whether the shutter and bellows are still functional.
