See previous two lots. These ten buttons are 1.25" to 2.25". All include "SDS" except row 3, #3. This also has some air under the celluloid. Only other defect is row 2, #2 with a few light tan marks and row 2, #3 with faint tanning on much of the pale bkg. Rest are Exc. to Mint. Row 1, #1 is from April 17, 1965 first "March On Washington" attended by about 25,000 protestors and this made SDS the lead anti-war group. Row 2, #2 is also an early item from October 1965. Many rarities.
