A very rare medal, in an unprecedented version - a one-sided print in silver.
Minted on a thicker disc than the standard one.
In addition, as noted in J. Strzałkowski's catalog, this is a different variant of the stamp (including a distinctly different typeface).
Signed on the rim by J. CHYLIŃSKI.
Silver, diameter 50 mm, weight 72.56 g.
