A collodion positive (ambrotype) of a young man with a hand cart advertising bakery goods for sale, taken by an unknown photographer in about 1860. The smartly dressed youth has a basket of bread over his shoulder and rests his elbow on a cart advertising 'The Hygienic Bakery Confectionery Co Ltd' based in Willesden, London. The collodion positive process (also commonly known as ambrotype) was popular during the 1850s and 1860s. An underexposed collodion negative on glass was backed with a black opaque coating to create a unique positive image.
