Sizes are 1.25” up to 6”. There are 33 pieces with most being pin-back buttons although one piece is a porcelain oval pin (end of row 2) and three pieces are magnets (bottom row, right). There is one exact duplicate (Row 3 #2) plus one electronic button (Row 5 #2) that no longer works due to some reverse corrosion. Top row of the group features buttons from the 60s-70s and many of these are quite scarce as well as are many of the more modern issues. Many feature great color. Vast majority are NM to Mint. A nice “boomer” era group.
