Brief aan anoniem Possibly 1807

"Brief aan anoniem" is a handwritten letter by Dutch artist Jan de Greef, likely written in 1807. The letter is written in Dutch and appears to be a request for information about a glass factory in the town of Gouda, Netherlands. This artwork, while not a painting or a drawing, provides a glimpse into the life of a well-known Dutch artist of the early 19th century and gives insight into his personal correspondence. It is a unique piece for those interested in the lives and letters of artists and the social history of the Netherlands.
