The exhibit, entitled “The Big Y: From Neighborhood Grocer to the Modern Supermarket,”is now on permanent view at the Wood Museum, and tells the story of community development and business innovation and how this local grocery store impacted the food industry. Through photos and memorabilia, the story of its evolution unfolds and connects visitors to a piece of western MA history.
