Single-sided sample print with the number 1.2.1.1946 perforated in the right margin.
Different from the one on which this denomination was printed ultimately. Here smoothed, slippery and shiny. Clearly white on the obverse side, but cream on the reverse.
A few fracture lines, but no rubbing or strong humps.
There is a sticky residue on the only surviving corner on the reverse side, presumably from pasting into a presentation/acceptance folder. Other corners torn off (probably left with the under-sticker by the folder).
A very rare, uncommon item. Print sample from the issue preparation process.
