Vintage Moscow commemorative pins, lot of 2

Description

Two commemorative pins labelled "MOCKBA" (Moscow).  They measure 1 inch by 3/4 inch and are in the original packaging.  The one with the "50" in the upper left also says "1941-1945" on the banner below the building.  Both backgrounds appear black in the photo but are navy blue.  Both pointed buildings are red.  Framing and backing might be metal but do not stick to a magnet.  These are believed to be vintage.
