Graphic Communications International Union, Local 48B, was originally chartered as a local of the International Brotherhood of Bookbinders. When the Bookbinders became a part of the Graphic Arts International Union in 1972, it adopted its current number, which it kept in the subsequent merger that produced the Graphic Communications International Union.

Local 48B represented over 1000 bindery workers in the Holyoke area, including workers at the National Blank Book Company, Eureka Blank Book, New England Bindery, and Hampden Glazed Paper and Card Company. Through the 1960's, the union and the companies engaged in relatively amicable collective bargaining negotiations, resulting in few arbitrations or strikes. A sizable portion of the local, however, became disenchanted with the local's leadership, complaining of poor contracts. Long-time leaders Philip Beaudry, Raymond Lacroix, and Robert Kelly came under attack, eventually giving way to Joe Brown and Richard Connors in the 1970's.

In the 1970's, a rank-and-file group, advocating a more activist role, nevertheless became sufficiently established in Local 48B to publish a newsletter and conduct opposition campaigns against Kelly, Brown, and Connors. The rank-and-file group finally succeeded in electing Warren Plaut as President in 1984.
