The picture below shows a larger view of all (27) Various Mixed Charity Group RibbonPins in this lot. This is an accumulated lot. These are not dated and the years that they were used or acquired are unknown. Only four of these are marked. They read as follows:
HOLOGIC
ASTRA ZENECA
SHU AIDS AWARENESS DAY
PASSIONATELY PINK FOR THE CURE A PROGRAM OF SUSAN G. KOMEN FOR THE CURE
All of these for one price! To judge the sizes the larger two top center pins each measure 2-1/16'' tall. These appear to be in mint condition as pictured.
