Cosmos is a late period pattern introduced by Roseville Pottery in 1939. Standard colors are blue, brown, and green. The blue tends to be the most popular today. Roseville Cosmos was typically marked with die-impressed marks, including the Roseville script, shape number, and size. Although advertisements mention 48 shapes, only 45 appear in factory stock pages. Shapes include baskets, bookends, bowls, cornucopias, jardini�res, pedestals, vases, candlesticks, etc.
