Size 212 x 99 mm (cut by hand from a larger sheet).
The paper is quite thick, cream shade, with UV glowing security threads. The paper type is different than the one ultimately used for the 500 zloty 1948, but with the same watermark as on the 500, only slightly scaled up, enlarged from the size it was placed on the circulating banknote.
This slight enlargement of the mark has its advantages. It is more precise and detailed in relation to the one we see on the 500th. The neck beads and collar details are better visible.
