These are all 1.25” from the 1940s and early 1950s. The one named “S.S. Richard Peck” comes with an exact duplicate while the other 18 are different although several ships have more than one image. Top three rows depict ferry boats while bottom two rows show ocean liners including a rare “Queen Mary” with text along right hand edge. Button in row 2 #2 has hairline crack otherwise all are NM displaying Mint. An outstanding group.
