Sizes are .75" to 1". The first and smallest "Safety First" button has pinpoint dot off bottom rim edge with a little light age on the back but still displays NM. Second item with "Vote Yes" has light stain by the reverse collet but only a tiny dot showing on the front edge. Cello does have some hairline scratches but quite light. Larger "Safety First" button has no back paper and with several long but hairline cello splits with the cello laying perfectly flat so the front of the piece still displays Mint with just a tiny air dot on bottom right barely showing. Scarce design. Last reading "Vote Dry, Yes" has Bastian paper and is Mint. Only the first item in this group is common, other three are scarce to rare.
