Here's a completely unused calendar of Asmussen's Jewellers in North Battleford, Saskatchewan.  If I'm not mistaken, he was Harold Asmussen.  The year is 1953 and the "flap" has never been folded up.  In the day, one either folded up the stiff card flap or tore it off, revealing the calendar pages.  Those were removed as time went on.

This measures 11 1/2" tall.

Good luck and thanks for looking at another sale by The Mighty Atom.
