Quoted from that above link:
Rubens Originals
"With its trademark Rubens "R" logo gracing its pieces, Rubens remains of the most recognizable head vase producers in the world. The company began as the U.S. Bag & Supply Company, founded in the 30s by Israel Steinman. His son, Reuben, took over in 1947, renamed the company Rubens Originals 9to mimic the spelling of the famous painter), and began importing art ware from Japan. After purchasing an elegant vase on a trip to Montreal, Reuben Steinman had the piece reproduced in three sizes; in 1956, the very first Rubens Original head vase was released. Based in Los Angeles, the company began distributing a variety of collectibles, such as floral pottery and giftware, ceramic and plastic accessories, and figurines. Today, Rubens Originals continues to import novelty pottery, floral containers and artificial silk flowers from Japan."See the example Marks there below this quote, on that link
