Their original items were signed with the initials "JB" on each pieces. Many JB objects are sold at auctions: http://www.chs.org/bookends .

In the early 1950's the Jennings Brothers Manufacturing Company went out of business and the art object casts were purchased by another company in Philadelphia, PA. They used the original JR casts to manufacture replicas which are cheaper versions of the original JR items sold at art auctions.
