14 items from 11/16" to 1.75". The first four items carry the name or initials of the Steel Workers Organizing Committee. This was organized in 1936 and used until 1942 when the group became United Steel Workers. The one tie bar in this group carries that latter name. The additional "C.I.O." items include the trades of "Federation Of Dyers," "Union Of Marine & Shipblg Workers," "Shipyard Workers Union," "I.U. of M.&S.W of A," "United Tobacco Workers Union," and "Textile Workers Organizing Committee." The last three items, one and duplicate, relate to 1940's Political Action Committees. The last two pieces dating 1948 would relate to Truman who the "C.I.O." endorsed. Trivial wear on a couple but all at least VF or better.
