For half of the 20th century, Ransburg products played a key role in decorating American homes and today are sought-after collectibles. As a tribute to their grandfather--Harper J. Ransburg, founder of the Ransburg Company--and as a resource for collectors, Dave and Tom Ransburg created the book The Ransburg Collection.
