PSP17: 1841c Salt Print – Calotype Radcliffe College Oxford by Fox Talbot Rare Circular Patent Stamp (Talbotype) – This is a rare early photograph by Henry Fox Talbot of Radcliffe Library in Oxford. It has a handwritten title, possibly by Fox Talbot and also a blue wetstamp that reads ‘Patent Talbotype Or Sun Picture. It is mounted onto a card mount. The image itself is 3 inches (76mm) x 2.5 inches (63mm).
This is not from the June 1846 Art Union edition but rather the much more sought after format sold by Nicolass Henneman. Henemann’s price in the top right corner has been removed from the piece.
This is an extremely rare salt print with only 5 known to exist (4 in Institutions and 1 Private).
Professor Larry Schaaf number this 1592 in his catalogue. The original resides in the British Library( LA3275B). NMeM has three prints from the Science Museum Collection, 1937-1734/1-3 and one from the Kodak, 1990-5170 (this one is dated of 18 June 1841). There is 1 known in a private collection within an album assembled by Talbot himself.
The image displays the usual fading and has a small piece missing at the bottom left. In late 1840, Talbot worked out a very different developing-out process (a concept pioneered by the daguerreotype process introduced in 1839). This major improvement was introduced to the public as the calotype or talbotype process in 1841. In February 1841, Talbot obtained an English patent for his developed-out calotype process. In August 1841 he licensed Henry Collen, the miniature painter, as the first professional calotypist. The calotype process was developed in 1840 by W.H.F. Talbot and patented in 1841. Another known print housed at the Art Institvte Chicago measures the same and show the library from the opposite side to this print: Radcliffe Library, Oxford, c. 1841/43. Salted paper print 7.2 x 6.3 cm (image/paper); 19.7 x 16.2 cm (mount)
