The Underwood Exhibition is an early large-format wooden plate camera, a class of equipment associated with the late 19th and early 20th century when mahogany-and-brass field cameras were standard professional tools. It was sold for studio and exhibition-style photographic work using glass plates.

Auction evidence for this model is thin: a single recorded UK saleroom result from 2017 hammered at £156, so any current 2026 value guidance has to be treated as indicative rather than a true market range. At hammer-price level, wooden plate cameras of this era typically trade on completeness of the bellows, lens and plate holders, and a comparable Underwood Exhibition today would likely sell for a broadly similar two-figure-to-low-three-figure sum unless paired with a desirable period lens.
