The holiday season is generally a reason to rejoice. Family and friends come together. People decorate their homes and offices. Shoppers flock to stores all over the city. And Chicago itself gets dressed up in lights, ribbons, wreaths and general revelry. While the holiday season seems to start earlier and earlier every year, there’s no denying that people get excited to celebrate the season each year. We thought it would be fun to look back over the decades and see how the city got dressed up for the Christmas season. Browse through the gallery above, courtesy of Calumet412.com.
