The Art Deco Society of California (ADSC) is dedicated to honoring the aesthetic and architectural achievements of the first half of the 20th century, especially the decades of the 1920's, 30's and 40's that is now known as the Art Deco period.

For 189 years the Butler-McCook House and Garden was home to four generations of a family who participated in, witnessed, and recorded the evolution of Main Street between the American Revolution and the mid-20th century. The house's exterior looks much as it did when it was built in 1782. Behind it is a restored Victorian ornamental garden, originally laid out in 1865. Inside are the original furnishings ranging from Connecticut-crafted colonial furniture to Victorian-era toys and paintings to samurai armor acquired during a trip to Japan. The objects were accumulated over the course of more than 125 years by members of this clan, which included physicians, industrialists, missionaries, artists, globe trotters, and pioneering educators and social reformers. The Main Street History Center's keystone exhibition, "Witnesses on Main Street," uses the Butler and McCook families' words and experiences to chronicle their neighborhood's transformation from a clutch of clapboard dwellings, taverns, and artisans' shops into a modern urban enclave of multistory steel, brick, and stone structures housing major financial, industrial, governmental, and cultural institutions.

The house offers exhibits and tours.
