Shown in the photos, a large 44 x 36 x 5 cm folder, inside of which cardboard cards with horizontal divisions.
All individually made, probably bookbinders and dedicated to storing notgelds.
Inside 41 cards, allow storing notgelds on both sides. On 3 of them small files of notgelds.
The whole for collectors of this type of banknotes can be an interesting form of presenting the collection in the atmosphere of the era.
The interior in good condition, but the outer cover of the whole detached from the rest, also for usability purposes probably requires bookbinding corrections.
