Ironworkers Local 401 has been erecting Philadelphia and Southeast Pennsylvania since 1925 – and the local celebrated its 100th Centennial Anniversary with a Dinner/Dance Gala on December 1, 2025, and the production of a special Local 401 100-Year History Program Book by UNION HISTORIES.
UNION HISTORIES produced the History Book and also provided a range of Design Services for the Local 401 event ... all of which were provided at NO COST to the local as we sold Ads for the History Book and Sponsorships for the Celebration Event, while also earning funds for the local!
