This is probably the largest vintage daguerreotype plate in the world.
The housing sizes are : 636 mm x 741x 24 mm. It is preserved in the National Media Museum collection in the UK and can be seen by appointment (Inv. n. 1934-649) .
Trying to take a daguerreotype of this size of a live person using a camera would have been extremely difficult. The exposure would be several minutes long. The plate may have been made by re-photographing a smaller image or a glass negative may have been used in its production.
Daguerreobase is an online application designed to contain detailed information about daguerreotypes. Members can view, edit and store records of individual daguerreotypes and establish relations to other records based on a wide range of characteristics. This includes collections, owners, creators, hallmarks, housing models, sizes, materials and free text descriptions.
