Unique and moving collector's item – an original celluloid box handmade by a prisoner during the Polish People's Republic period. This artifact is an extraordinary testament to so-called "prison art", a form of creativity in which limited resources and difficult conditions gave rise to unique, often symbolic, utilitarian objects. The box, made from celluloid characteristic of the mid-20th century, bears traces of handcrafting. Its shape, joins, and finish reveal work done under conditions of limited access to tools, giving it an authentic, raw character. Such items, created in penal institutions, often made their way to the outside world as souvenirs or barter goods, now becoming valuable documents of the era and human fates. Who is this item for?

• Collectors of PRL relics – as a material trace of daily life and customs of that period.
• Enthusiasts of non-professional and folk art – as an example of creativity under extremely difficult conditions.
• Collectors of 20th-century social history – the item serves as a starting point for stories about the penitentiary system, prisoners' lives, and the unofficial economy of those years.

The box is more than a utilitarian object – it is a story enclosed in material. Its collector value stems from its authenticity, history, and the rarity of such objects on the antique market. It is a unique addition to a collection dedicated to the Polish People's Republic, ethnography, or outsider art.
