Vier portretten before 1893

"Vier portretten" is an anonymous collection of four portraits, likely created before 1893. This collection consists of four black and white photographic portraits, likely made with the daguerreotype process, an early photographic technique that was popular during the 19th century. The portraits are displayed in an open book with captions in French. The collection provides insight into the development of photography and portraiture during this time.
