The Talbot Errtee button tintype camera is a late 19th / early 20th century specialist tintype camera designed for producing small ferrotype portraits, of the type used by itinerant street and fairground photographers. It is a niche piece of photographic history rather than a general-purpose camera, and surviving examples are scarce.

Auction evidence for the Talbot Errtee button tintype is very thin: a single UK saleroom result from 2018 shows a hammer price of £840, which gives the only firm wholesale data point for what one is worth today. With just one recorded sale, there is no meaningful range or median to quote, and any current value estimate should be treated as indicative — condition, completeness of the original fittings, and provenance will heavily influence what a comparable example sells for in the present market.
